Tom Boucher 4361d83279 perf(#314 ): index roadmap plan lookups by id (O(lines×plans) → O(lines+plans)) (#396 )

Hot path in cmdRoadmapAnnotateDependencies called planData.find() on every
checklist line. Replaced with a first-wins Map built once before the loop so
each line resolves in O(1); first-wins preserves exact .find() semantics and
null-on-miss → wave-1 default is unchanged.

Fixes #314
