gsxdsm ebe514c3e4 FN-8677: propagate task update lanes before conversion

Propagate cache-warmed workflow lanes through task updates so synchronous engine consumers support renamed boards.

- Add task lane cache and attach resolved lanes to task:updated metadata.
- Update scheduler, triage, and notification consumers to use carried lanes with bridge-safe fallbacks.
- Cover lane propagation and renamed-lane event behavior with core and engine tests.
