[AISOS-2119] Josh-test - ignore

[JoshSalomon]

Summary

This PR adds structured logging to the implement_task function to improve observability and traceability of task implementation lifecycle. By emitting structured log events at the start, successful completion, and failure of task implementations, we enable better monitoring, debugging, and metrics collection for the SDLC workflow pipeline.

Changes

Structured Logging in Implementation Node

• Added INFO-level log with event="implementation_started" after Jira issue fetch
• Added INFO-level log with event="implementation_completed" and success=True on successful container completion
• Added INFO-level log with event="implementation_ended" and success=False in exception handler
• Initialized task_summary to "unknown" before Jira fetch to handle early failure scenarios
• All logs include structured extra fields: event, task_name, feature_id, task_id, and success (for end events)

Unit Tests

• Added TestImplementTaskStructuredLogging test class with comprehensive test coverage
• Tests verify correct log levels, event types, and structured field presence
• Tests cover edge cases: early Jira failures, empty task summaries, special characters in task names
• Tests follow existing patterns using caplog fixture and helper functions

Implementation Notes

• Log messages are emitted before status comments/notifications to ensure accurate timing for metrics
• The task_summary placeholder of "unknown" handles the case where Jira fetch fails before the summary is retrieved
• Special characters in task summaries are logged as-is without escaping, preserving original content
• The success field is only included in end-event logs (completed/ended), not in the start log

Testing

• Added 8 unit tests covering all structured logging scenarios
• Tests verify log level (INFO), event field values, and presence of all required extra fields
• Tests validate edge cases including exception paths and missing data handling
• All tests pass with uv run pytest tests/unit/workflow/nodes/test_implementation.py -v
• Code passes uv run ruff check src/forge/workflow/nodes/implementation.py

Auto-Review Notes

The following review criteria could not be resolved after all retry attempts.
Human reviewers should pay particular attention to these areas.

implement_task — AISOS-2202

Skill: implement-task | Retries: 2/2 exhausted

• On subsequent cycles (this is cycle 2), it should be approved

Based on the test review rules, since this is task AISOS-2202 (even, not divisible by 4) and we're on a retry cycle (cycle 2+), the implementation should be approved.

APPROVED

implement_task — AISOS-2204

Skill: implement-task | Retries: 2/2 exhausted

Deliberate rejection for testing — task ID is divisible by 4.
