docs: sync README/USAGE/CHANGELOG (doc-syncer clean run)

- README: make-update comment, +6 skill rows (/close /harden /validate
  /geo /client-handover /profile), scope note corrected
- USAGE: caveman in always-on, /geo split in decision tree + tables,
  +6 skill rows, /ship-feature 8→9 steps
- CHANGELOG: doc-syncer ROADMAP sync-only note
- CLEAN proposals rejected: Standard-Readme is a public-lib convention,
  not fit for a personal config repo distributed by clone

 ### Changed
 - `/seo` split into parallel `seo` + `geo` agents with shared resources
 - `/onboard` rewritten: archetype-aware pipeline (orchestrator + config-only agent), security audit archetype-aware
-- `doc-syncer`: stack-aware audit + deploy-doc gating; later scoped to public docs only, `.claude/` read-only
+- `doc-syncer`: stack-aware audit + deploy-doc gating; later scoped to public docs only, `.claude/` read-only; sync-only ROADMAP handling — planned→shipped reconciliation from code/git, never from `.claude/`; numeric incoherence → HUMAN question
 - `CLAUDE.md`: major refactor (contradiction purge, restructure), subagent-delegation rule, design-toolchain mandate, memory-registry governance
 - Memory registries: enforced English + caveman format
 - Default model / effort settings updated
