Review: Marking features as planned — incorrect premise

Issue

This PR marks Agent evolution and Meta-planning as (planned), but both features are actually implemented:

• src/services/evolution_loop.rs — 1,229 lines implementing success rate tracking, template refinement triggering, auto-reversion on regression, and rolling window evaluation
• src/services/meta_planner.rs — 416 lines implementing task analysis, capability gap detection, and specialist agent spawning

These are substantial, working implementations — not stubs or placeholders.

What to do instead

The original issue (#63) was filed based on a surface-level grep that missed the actual implementations. The issue itself should be closed as "not a bug" rather than addressed by incorrectly marking working features as planned.

I'm rejecting this PR because merging it would make the README less accurate, not more.
