feat(actions): add get_job to read a single Actions job (#211)

Adds a read-only `get_job` method to the `actions_run_read` tool. `actions_run_read` could already `list_jobs` / `list_run_jobs` (slimmed lists) and read job logs by `job_id`, but there was no way to fetch the full detail of one job. `get_job` closes that gap.Reviewed-on: https://gitea.com/gitea/gitea-mcp/pulls/211
