fix(governance): resolve lint, unit_tests CI failures in cost budget tracking
- Remove triple blank line in steps file (ruff format E303)
- Collapse multiline if conditions in cost_tracking.py (ruff format)
- Add BudgetExceededError to __all__ in exceptions.py
- Fix step_check_budget to pass context.org_accumulator instead of None
- Fix Three-tier scenario amounts so org budget fails first (session $200, org $100)
- Disambiguate @when step using {cost:f} type specifier to avoid AmbiguousStep
- Rename duplicate @then step to avoid conflict with lsp_registry_steps.py
- Add missing column header rows to Gherkin tables in feature file

Feature: Cost and Session Budget Tracking and Enforcement
Background:
Given a cost tracking service is initialized
And a session cost budget of $10.00 is configured
And a cost metadata tracker is created
Scenario: Track cost usage after LLM call
When an LLM call costs $2.50 with 100 input tokens and 50 output tokens
Then the cost metadata should show:
| field | value |
| total_cost | 2.50 |
| total_tokens | 150 |
| input_tokens | 100 |
| output_tokens | 50 |
And the session budget should show $7.50 remaining
Scenario: Enforce budget limit when exceeded
Given the session budget is $5.00
When an LLM call costs $3.00
And another LLM call costs $2.50
Then the second call should raise BudgetExceededError
And the error should indicate plan budget exceeded
Scenario: Track provider costs separately
When an LLM call from OpenAI costs $1.50
And an LLM call from Anthropic costs $2.00
Then the cost metadata should show provider breakdown:
| provider | cost |
| openai | 1.50 |
| anthropic | 2.00 |
Scenario: Query budget status
Given the session budget is $10.00
When $3.50 has been spent
Then budget status should show:
| field | value |
| limit | 10.00 |
| used | 3.50 |
| remaining | 6.50 |
| utilization | 0.35 |
Scenario: Warn at 90% budget utilization
Given the session budget is $10.00
When $9.00 has been spent
And a check for $0.50 cost is performed
Then the budget check should return warning=true
And the check should still be allowed
Scenario: Record budget exhaustion events
Given the session budget is $5.00
When an LLM call costs $5.50 from OpenAI using gpt-4o
Then a BudgetExceededError should be raised
And the cost metadata should record an exhaustion event with:
| field | value |
| budget_type | session |
| limit | 5.00 |
| used | 5.50 |
| provider | openai |
| model | gpt-4o |
Scenario: Handle unlimited budgets
Given no session budget is configured
When multiple LLM calls totaling $100.00 are made
Then all calls should succeed
And the cost metadata should track the total cost
Scenario: Three-tier budget hierarchy
Given a session budget of $200.00
And an organization budget of $100.00
When $10.00 has been spent at session level
And $82.00 has been spent at organization level
And a check for $15.00 cost is performed
Then the check should fail due to organization budget
And the exceeded_level should be "org"
Scenario: Budget check with negative cost
When a budget check is performed with a negative cost
Then a ValueError should be raised for cost validation
Scenario: Record cost with invalid tokens
When recording cost with negative input tokens
Then a ValueError should be raised for cost validation
