Updated ECC notes to match the current state of affaan-m/everything-claude-code
docs/token-optimization.md and docs/SKILL-PLACEMENT-POLICY.md:
- Drop CLAUDE_AUTOCOMPACT_PCT_OVERRIDE recommendations (now warned against
upstream — variable can only lower threshold, opposite of intent)
- Add CLAUDE_CODE_SUBAGENT_MODEL=haiku as the new core token-saving setting
- Flag the default `memory` MCP for disablement (no skill/agent/hook references)
- Add Skill Placement Policy section (curated/learned/imported/evolved + provenance)
- Cover missing commands: /checkpoint, /sessions, /security-scan, /claw, /projects
Add new resource: ECC 编排实战手册.md (721 lines). Six orchestration patterns
(dmux+worktree, sequential claude -p, continuous-claude, Ralphinho RFC-DAG,
santa-loop, Task in-process) with real commands, real plan.json structures,
real CLI flags, and explicit "could not verify online" markers for /multi-*
and /feature-dev. All sourced to specific commands/*.md or skills/*.md files.
