Commit Message: feat(tui): implement ContentsGrid with typed block widgets for conversation stream
Branch: feat/tui-contents-grid-block-widgets

Background and Context

During UAT testing of the TuiMaterializer A2A Integration feature area, it was discovered that the ContentsGrid widget does not exist in the codebase. The spec requires that ContentsGrid serves as the typed block widget container in the TUI conversation stream, using typed block widgets: ThoughtBlockWidget, ToolCallWidget, ToolResultWidget, TextBlockWidget, ErrorBlockWidget, and PermissionQuestionWidget.

Evidence of the missing implementation:

No ContentsGrid class exists anywhere in src/cleveragents/tui/
The following required block widgets are also missing from src/cleveragents/tui/widgets/:
- ToolCallWidget — not present
- ToolResultWidget — not present
- TextBlockWidget — not present
- ErrorBlockWidget — not present
Only ThoughtBlockWidget and PermissionQuestionWidget exist
The current TUI app uses a plain _Static widget for the conversation area instead of a typed ContentsGrid

Expected Behavior

Per the TuiMaterializer A2A Integration specification:

A ContentsGrid widget must exist that serves as the conversation stream container
ContentsGrid must use typed block widgets:
- ThoughtBlockWidget — for actor reasoning traces (already exists)
- ToolCallWidget — for tool invocation display
- ToolResultWidget — for tool result display
- TextBlockWidget — for plain text content blocks
- ErrorBlockWidget — for error display
- PermissionQuestionWidget — for inline permission requests (already exists)
The CleverAgentsTuiApp must use ContentsGrid as the conversation area widget

Actual Behavior

ContentsGrid does not exist
ToolCallWidget, ToolResultWidget, TextBlockWidget, ErrorBlockWidget do not exist
The TUI app uses _Static("CleverAgents TUI", id="conversation") as a plain static widget
No typed block rendering is possible in the current implementation

Steps to Reproduce

from cleveragents.tui.widgets import ToolCallWidget
# ImportError: cannot import name 'ToolCallWidget' from 'cleveragents.tui.widgets'

Acceptance Criteria

ContentsGrid widget exists in src/cleveragents/tui/widgets/contents_grid.py
ToolCallWidget exists in src/cleveragents/tui/widgets/tool_call.py
ToolResultWidget exists in src/cleveragents/tui/widgets/tool_result.py
TextBlockWidget exists in src/cleveragents/tui/widgets/text_block.py
ErrorBlockWidget exists in src/cleveragents/tui/widgets/error_block.py
All new widgets are exported from cleveragents.tui.widgets
CleverAgentsTuiApp uses ContentsGrid as the conversation area
New Behave BDD scenarios cover ContentsGrid block widget rendering
Coverage remains >= 97%

Subtasks

Create src/cleveragents/tui/widgets/contents_grid.py with ContentsGrid class
Create src/cleveragents/tui/widgets/tool_call.py with ToolCallWidget class
Create src/cleveragents/tui/widgets/tool_result.py with ToolResultWidget class
Create src/cleveragents/tui/widgets/text_block.py with TextBlockWidget class
Create src/cleveragents/tui/widgets/error_block.py with ErrorBlockWidget class
Export all new widgets from cleveragents.tui.widgets.__init__
Update CleverAgentsTuiApp.compose() to use ContentsGrid instead of _Static
Add Behave BDD scenarios for ContentsGrid and each new block widget
Verify coverage >= 97% via nox -s coverage_report
Run nox (all default sessions), fix any errors

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly, followed by a blank line, then additional lines providing relevant details about the implementation.
