Add API endpoints for Forgejo Actions job information and log retrieval,
addressing the limitation where job data was only available through the
web UI with session authentication.
New endpoints:
- GET /api/v1/repos/{owner}/{repo}/actions/runs/{run}/jobs/{job}
Returns job information including status, timestamps, and steps
- GET /api/v1/repos/{owner}/{repo}/actions/runs/{run}/jobs/{job}/logs
Returns job logs with support for partial retrieval
Log retrieval query parameters:
- head=N: Return first N lines of the log
- tail=N: Return last N lines of the log
- offset=M: Skip M lines (with head) or skip to M lines from end (with tail)
- format=json: Return structured JSON with line numbers and timestamps
Implementation includes API response types (ActionJobResponse, ActionJobStep,
ActionRunSummary), efficient line-based operations for partial log reading,
integration tests, and Swagger documentation.
The endpoints use standard API token authentication and follow Forgejo's
existing API patterns. Job indices are 0-based matching the web UI behaviour.
