chore: consolidate org-common Claude Code content from audit

[wcmchenry3-stack]

Context

After running the audit script (#87), some target repos may contain Claude Code content (.claude/ files) that was added locally and never upstreamed to the meta-repo. If those files are org-common (useful for all repos), they should be moved to the meta-repo and added to the FILE_MAP so they're synced everywhere consistently.

This issue is the remediation step after the audit.

Implementation

1. Review audit output from issue feat: add audit script to discover unsynced Claude Code content in org repos #87
2. For each file flagged as "in repo, NOT in FILE_MAP":
   • Determine if it's org-common (belongs in meta-repo) or repo-specific (should stay)
   • If org-common: copy to meta-repo .claude/ directory and add to FILE_MAP
   • If repo-specific: document why it's excluded from sync (add to "What NOT to sync" section in README)
3. Trigger sync (sync-community-health.yml with force: true) to push consolidated content to all repos
4. Verify each target repo received the expected files

Acceptance Criteria

• Audit output (feat: add audit script to discover unsynced Claude Code content in org repos #87) reviewed and triaged
• All org-common Claude Code files upstreamed to meta-repo
• FILE_MAP updated for any newly added files
• Repo-specific files documented as intentionally excluded
• Sync workflow triggered and PRs opened in all 6 target repos
• No Claude Code content exists in target repos that should be in meta-repo

Dependencies

BLOCKED by issue #87 (audit script must run first to identify what needs consolidating).
