FN-6966: flag stale timing metadata in velocity reports

Browse Source 
Add stale timing context to the weekly test velocity baseline so W26 regressions are not misattributed.

- Report timing snapshot age and missing slowest-file paths before the slow-file table.
- Persist timing metadata notes in velocity history and regenerate the W26 baseline report.
- Cover stale and missing timing metadata warnings with node:test assertions.

- None recorded.
## Timing snapshot notes
- Timing snapshot is 19 days old; verify slowest-file attribution before treating the table as the current culprit.
- 5 of the listed slowest files no longer exist at the recorded paths: `packages/engine/src/__tests__/reliability-interactions/shared-branch-group-lifecycle.test.ts`, `packages/engine/src/__tests__/reliability-interactions/branch-group-automerge-precedence.test.ts`, `packages/engine/src/__tests__/reliability-interactions/branch-group-merge-routing.test.ts`, `packages/engine/src/__tests__/reliability-interactions/branch-group-promotion-gate.test.ts`, `packages/engine/src/__tests__/reliability-interactions/branch-group-promotion.test.ts`.
