test(tui): add BDD tests for multi-session tabs feature

- Added comprehensive feature file with 10 scenarios covering:
  - Session creation and management
  - Session switching and closing
  - Independent persona tracking per session
  - Independent transcript per session
  - Session renaming and timestamp tracking
- Implemented step definitions for all scenarios
- Tests verify multi-session functionality without requiring Textual UI

Feature: Budget enforcement in PlanExecutor
As a platform operator
I want PlanExecutor to halt execution when budget limits are exceeded
So that autonomous agents cannot overspend configured limits
# ------------------------------------------------------------------
# BudgetExceededError and PlanBudgetExceededError exceptions
# ------------------------------------------------------------------
Scenario: BudgetExceededError has correct attributes
When I create a BudgetExceededError with plan_id "plan-1" budget_type "daily" used 5.0 limit 3.0
Then the BudgetExceededError plan_id should be "plan-1"
And the BudgetExceededError budget_type should be "daily"
And the BudgetExceededError used should be 5.0
And the BudgetExceededError limit should be 3.0
And the BudgetExceededError message should contain "budget"
Scenario: PlanBudgetExceededError has correct attributes
When I create a PlanBudgetExceededError with plan_id "plan-2" used 10.0 limit 5.0
Then the PlanBudgetExceededError plan_id should be "plan-2"
And the PlanBudgetExceededError used should be 10.0
And the PlanBudgetExceededError limit should be 5.0
And the PlanBudgetExceededError message should contain "budget"
Scenario: BudgetExceededError is a subclass of PlanError
When I create a BudgetExceededError with plan_id "plan-3" budget_type "session" used 1.0 limit 0.5
Then the BudgetExceededError should be an instance of PlanError
Scenario: PlanBudgetExceededError is a subclass of PlanError
When I create a PlanBudgetExceededError with plan_id "plan-4" used 2.0 limit 1.0
Then the PlanBudgetExceededError should be an instance of PlanError
# ------------------------------------------------------------------
# PlanExecutor budget enforcement - no cost tracker (no-op)
# ------------------------------------------------------------------
Scenario: PlanExecutor without cost_tracker does not check budget
Given a budget enforcement PlanExecutor without cost_tracker
And a budget enforcement plan in Execute-Queued state
When I run budget enforcement execute
Then the budget enforcement execute should succeed without budget error
# ------------------------------------------------------------------
# PlanExecutor budget enforcement - plan budget exceeded
# ------------------------------------------------------------------
Scenario: PlanExecutor halts with PlanBudgetExceededError when plan budget exceeded
Given a budget enforcement PlanExecutor with plan budget 0.0001
And a budget enforcement plan in Execute-Queued state
And the cost_metadata has total_cost 0.001
When I run budget enforcement execute expecting budget error
Then a PlanBudgetExceededError should be raised
And the PlanBudgetExceededError plan_id should match the plan
Scenario: PlanExecutor saves plan state before halting on plan budget exceeded
Given a budget enforcement PlanExecutor with plan budget 0.0001
And a budget enforcement plan in Execute-Queued state
And the cost_metadata has total_cost 0.001
When I run budget enforcement execute expecting budget error
Then the lifecycle _commit_plan should have been called with budget_halt details
# ------------------------------------------------------------------
# PlanExecutor budget enforcement - daily budget exceeded
# ------------------------------------------------------------------
Scenario: PlanExecutor halts with BudgetExceededError when daily budget exceeded
Given a budget enforcement PlanExecutor with daily budget 0.0001
And a budget enforcement plan in Execute-Queued state
And the daily spend is 0.001
When I run budget enforcement execute expecting budget error
Then a BudgetExceededError should be raised
And the BudgetExceededError budget_type should be "daily"
Scenario: PlanExecutor saves plan state before halting on daily budget exceeded
Given a budget enforcement PlanExecutor with daily budget 0.0001
And a budget enforcement plan in Execute-Queued state
And the daily spend is 0.001
When I run budget enforcement execute expecting budget error
Then the lifecycle _commit_plan should have been called with budget_halt details
# ------------------------------------------------------------------
# PlanExecutor budget enforcement - within budget (no halt)
# ------------------------------------------------------------------
Scenario: PlanExecutor continues when plan budget is not exceeded
Given a budget enforcement PlanExecutor with plan budget 100.0
And a budget enforcement plan in Execute-Queued state
And the cost_metadata has total_cost 0.001
When I run budget enforcement execute
Then the budget enforcement execute should succeed without budget error
Scenario: PlanExecutor continues when daily budget is not exceeded
Given a budget enforcement PlanExecutor with daily budget 100.0
And a budget enforcement plan in Execute-Queued state
And the daily spend is 0.001
When I run budget enforcement execute
Then the budget enforcement execute should succeed without budget error
# ------------------------------------------------------------------
# AutomationProfile budget fields
# ------------------------------------------------------------------
Scenario: AutomationProfile has budget_per_plan field
When I create an AutomationProfile with budget_per_plan 10.0
Then the AutomationProfile budget_per_plan should be 10.0
Scenario: AutomationProfile has budget_per_session field
When I create an AutomationProfile with budget_per_session 50.0
Then the AutomationProfile budget_per_session should be 50.0
Scenario: AutomationProfile budget_per_plan defaults to None
When I create an AutomationProfile with default budget fields
Then the AutomationProfile budget_per_plan should be None
And the AutomationProfile budget_per_session should be None
Scenario: AutomationProfile rejects negative budget_per_plan
When I try to create an AutomationProfile with budget_per_plan -1.0
Then a budget enforcement validation error should be raised
Scenario: AutomationProfile rejects negative budget_per_session
When I try to create an AutomationProfile with budget_per_session -1.0
Then a budget enforcement validation error should be raised
# ------------------------------------------------------------------
# _check_budget method - direct unit tests
# ------------------------------------------------------------------
Scenario: _check_budget is a no-op when cost_tracker is None
Given a budget enforcement PlanExecutor without cost_tracker
When I call _check_budget directly with plan_id "test-plan"
Then no budget exception should be raised
Scenario: _check_budget raises PlanBudgetExceededError when plan budget exceeded
Given a budget enforcement PlanExecutor with plan budget 0.0001
And the cost_metadata has total_cost 0.001
When I call _check_budget directly with plan_id "test-plan"
Then a PlanBudgetExceededError should be raised
Scenario: _check_budget raises BudgetExceededError when daily budget exceeded
Given a budget enforcement PlanExecutor with daily budget 0.0001
And the daily spend is 0.001
When I call _check_budget directly with plan_id "test-plan"
Then a BudgetExceededError should be raised
Scenario: _check_budget creates CostMetadata when none provided
Given a budget enforcement PlanExecutor with plan budget 100.0 and no cost_metadata
When I call _check_budget directly with plan_id "test-plan"
Then no budget exception should be raised
# ------------------------------------------------------------------
# _save_plan_state_on_budget_halt - graceful halt
# ------------------------------------------------------------------
Scenario: _save_plan_state_on_budget_halt persists budget details to plan
Given a budget enforcement PlanExecutor without cost_tracker
When I call _save_plan_state_on_budget_halt with plan_id "halt-plan" budget_type "plan" used 5.0 limit 3.0
Then the lifecycle _commit_plan should have been called
And the plan error_details should contain budget_halt true
And the plan error_details should contain budget_type "plan"
Scenario: _save_plan_state_on_budget_halt is non-fatal on lifecycle error
Given a budget enforcement PlanExecutor with failing lifecycle
When I call _save_plan_state_on_budget_halt with plan_id "halt-plan" budget_type "daily" used 1.0 limit 0.5
Then no exception should be raised from _save_plan_state_on_budget_halt

Feature: TUI Multi-Session Tabs with Independent A2A Bindings
The TUI supports multiple session tabs, each with independent A2A bindings,
persona selection, and conversation history.
Background:
Given a TUI app is initialized with multi-session support
Scenario: TUI starts with a default session
When the TUI app is created
Then the app should have exactly 1 session
And the active session should have session_id "default"
And the active session should have name "Default"
Scenario: Create a new session
Given the TUI app has 1 session
When I create a new session with name "Session 2"
Then the app should have exactly 2 sessions
And the active session should have name "Session 2"
And the new session should have an independent session_id
Scenario: Switch between sessions
Given the TUI app has 2 sessions
And the first session has session_id "default"
And the second session has session_id "sess-2"
When I switch to session "default"
Then the active session should have session_id "default"
When I switch to session "sess-2"
Then the active session should have session_id "sess-2"
Scenario: Close a session
Given the TUI app has 2 sessions
When I close the session with session_id "sess-2"
Then the app should have exactly 1 session
And the active session should have session_id "default"
Scenario: Cannot close the last session
Given the TUI app has 1 session
When I try to close the session with session_id "default"
Then the close operation should fail
And the app should still have exactly 1 session
Scenario: Rename a session
Given the TUI app has 1 session
And the active session has name "Default"
When I rename the session to "My Session"
Then the active session should have name "My Session"
Scenario: Each session has independent persona tracking
Given the TUI app has 2 sessions
And the first session is active
When I set persona "analyst" for the first session
And I switch to the second session
And I set persona "coder" for the second session
And I switch back to the first session
Then the first session should have active persona "analyst"
When I switch to the second session
Then the second session should have active persona "coder"
Scenario: Each session has independent transcript
Given the TUI app has 2 sessions
And the first session is active
When I add message "Hello from session 1" to the first session
And I switch to the second session
And I add message "Hello from session 2" to the second session
Then the first session transcript should contain "Hello from session 1"
And the first session transcript should not contain "Hello from session 2"
And the second session transcript should contain "Hello from session 2"
And the second session transcript should not contain "Hello from session 1"
Scenario: Session creation includes timestamp
When I create a new session
Then the new session should have a created_at timestamp in ISO format
