Sprint 3 plan and docs: adopt canonical annotation system from annotations/Memory strategy.md
- Add Sprint 3 plan (37 steps, global 39-75) with canonical memory annotations,
test quality requirements, global step numbering, and Sprint 2 overlap notes
- Refactor all docs to use canonical annotation families (@Deallocate, @Lifetime,
@Reclaim, @Owner, @Allocate) replacing simplified @deref 4-strategy system
- Replace @perf with canonical @Hot/@Cold, @Inline, @Pure from annotations/6 optimization
- Replace @memory-footprint, @execution-mode, @deref-explicit with canonical equivalents
- Update REQUIREMENTS_OVERVIEW, SPRINT_1_REQUIREMENTS, SPRINT_2_PLAN, SPRINT_2_VISION,
C++ Implementation Roadmap, example files, and progress report
- Remove duplicate bonus steps 41-42, consolidate Phase 3h from 7 to 4 steps
