## Summary
Implement the missing `continue_session()` method in SessionManager that enables continuing a session without a new prompt.

## Background
The router endpoint `POST /v1/sessions/{id}/continue` exists (lines 536-590 in sessions.py) but calls `session_manager.continue_session()` which does not exist. This causes an AttributeError at runtime.

## Implementation

Add to `src/cli_agent_api/services/session_manager.py`:

```python
async def continue_session(
    self,
    session_id: str,
) -> SessionActionResponse:
    """Continue a session without a new prompt.
    
    Re-runs the last context of a completed session, useful for
    retrying after failures or continuing interrupted work.
    
    Args:
        session_id: The session to continue.
        
    Returns:
        SessionActionResponse with current status.
        
    Raises:
        SessionNotFoundError: If session doesn't exist.
        SessionNotCompletedError: If session is not in continuable state.
    """
```

The method should:
1. Get the original session and validate it's completed/failed/cancelled
2. Create a new SessionConfig copying relevant fields (working_dir, model, etc.)
3. Add `--continue` flag and `--session-id <id>` to the config
4. Start new Claude process via `create_session()`
5. Return SessionActionResponse

## Files to Modify
- `src/cli_agent_api/services/session_manager.py` - Add method (~50 lines)
- `src/cli_agent_api/models/session.py` - May need to add continue_session flag to SessionConfig
- `tests/unit/test_session_manager.py` - Add tests (~40 lines)

## Acceptance Criteria
- [ ] `continue_session()` method exists in SessionManager
- [ ] Calling `POST /v1/sessions/{id}/continue` no longer crashes with AttributeError
- [ ] Method validates session is in continuable state
- [ ] 4+ unit tests added covering: success, not-found, not-continuable states

## QA Instructions
1. Run `pytest tests/unit/test_session_manager.py -v -k continue` - all tests pass
2. Start server, create a session, let it complete, then call continue endpoint
3. Verify no AttributeError occurs
4. Check that continued session starts running

## Implementation Complete ### Changes Made: 1. **Added `continue_session_id` field to SessionConfig** (models/session.py:150) - New optional field for the `--continue` CLI flag 2. **Updated ClaudeWrapper.build_command()** (services/claude.py:304-306) - Handles the new `continue_session_id` field - Adds `--continue <session_id>` to the command 3. **Implemented `continue_session()` method** (services/session_manager.py:593-670) - Validates session is in completed/failed/cancelled state - Creates new session with original config + `continue_session_id` - Returns SessionActionResponse with new session ID 4. **Added 7 unit tests** (tests/unit/test_session_manager.py) - test_build_command_with_continue - test_continue_session_not_found - test_continue_session_not_completed - test_continue_completed_session - test_continue_failed_session - test_continue_cancelled_session - test_continue_copies_config_fields ### Test Results: - All 7 new tests pass - All 816 unit tests pass - No regressions ### Verification: - `POST /v1/sessions/{id}/continue` endpoint now works without AttributeError - The method correctly validates session state before continuing - All original config fields are copied to the new session

## Feature Triage Complete **Status:** NOT IMPLEMENTED - Router endpoint exists but SessionManager method is missing **Summary:** The `POST /v1/sessions/{id}/continue` endpoint exists (sessions.py:536-590) but calls a non-existent `session_manager.continue_session()` method, causing AttributeError at runtime. Implementation should follow the existing `resume_session()` pattern. **Implementation Location:** - Add `continue_session_id` field to SessionConfig (models/session.py) - Handle field in ClaudeWrapper.build_command() (services/claude.py) - Add `continue_session()` method to SessionManager (services/session_manager.py) - Add unit tests (tests/unit/test_session_manager.py) **Complexity:** Low - straightforward implementation following existing patterns (~100 lines total) See attached triage report for full details including code pattern reference.
