Failed subagent runs left throwaway helpers (_encode_commit_payload.py,
_emit_payload.py) in the shared working tree, polluting git status and
tripping gitea_lock_issue / pre-flight purity gates.
Add an 'Agent temp artifact cleanup' runbook section requiring deletion
of _encode_*/_emit_*/_inline_* helpers when the MCP commit completes or
aborts, prefer scratchpad payload preparation, and document the cleanup
checklist. Back it with .gitignore patterns so strays cannot block
issue locks for later sessions, and pin both with doc-contract tests
(including a repo-root scan asserting the artifacts stay removed).
