Implement registration UX wishlist W1–W6 (260224)

W1: Document user-scope MCP config location in ~/.claude/CLAUDE.md —
    adds verification and re-registration commands, warns against
    settings.json (saves ~12K tokens per registration session).

W2: scripts/register_project.sh + make register-project —
    5-step automation: API health → topic lookup → MCP check →
    CLAUDE.md from template → progress event.

W3: state-hub/scripts/project_claude_md.template —
    parameterised CLAUDE.md with {PROJECT_NAME}/{DOMAIN}/{TOPIC_ID}
    placeholders; used by register_project.sh.

W4: Add custodian_topic_id + domain to all 6 canon project charters —
    lets agents grep for topic IDs without touching the API.

W5: state-hub/mcp_server/TOOLS.md — compact 30-line tool reference
    card; replaces reading the full server.py (~350 lines).

W6: Switch .mcp.json to absolute path + PYTHONPATH env so cwd is not
    required; add scripts/patch_mcp_cwd.py for post-registration fix.
    Update ~/.claude.json to match (cwd kept for belt-and-suspenders).

W7 (SessionStart hook) deferred: no SessionStart hook type in Claude
    Code; PreToolUse with empty matcher fires before every tool call.
