FN-7050: repair route and executor line ceilings

Repair the line-count ratchet baseline for focused route and executor drift.

- Add FN-7050 context to the line-count guardrail comments.
- Raise only the routes.ts and executor.ts grandfathered ceilings to match current drift.
- Preserve unrelated baseline entries for separate scoped repairs.

Wholesale god-file shrink remains long-term deferred work for dedicated refactors, and unrelated line-count violations must not be bundled into this scoped repair.
