gsxdsm 4e6df035c1 FN-6275: allow verified no-op completions

Allow executors to finish already-satisfied tasks without fabricating commits while preserving existing completion guards.

- Add leading sentinel parsing for premise-stale, no-op, duplicate, and redundant completion summaries.
- Permit zero-commit fn_task_done only for recognized sentinels or existing no-commit contracts, with audit log/activity details.
- Document the verified no-op completion contract and add regression coverage for accepted and refused paths.
