Fixes#4607
- Add property to Task that combines the deterministic
(MD5 of description+expected_output) with the unique instance uid=1000(ubuntu) gid=1000(ubuntu) groups=1000(ubuntu),27(sudo),999(docker)
(uuid4) to produce a collision-resistant identifier per execution.
- Update telemetry utils and spans to emit alongside
the existing and attributes.
- Keep unchanged for structural identity (crew composition,
copy/clone mapping).
- Add regression tests asserting unique run_ids across repeated
runs with identical task definitions.
