chore: M12 docs sync + .gitignore + erd (#15)

* docs: update MCP-tools list to 16 (add M12 authoring tools)

scrum4me-mcp PR #2 (gemerged) voegde drie authoring tools toe: create_pbi,
create_story, create_task. CLAUDE.md MCP-integratie-sectie reflecteert dat:
- Tools-count 13 → 16
- Nieuwe categorie "Authoring (PBI/Story/Task aanmaken)" met input-shapes
- create_todo verplaatst naar Authoring-categorie (logischer dan task/story-writes)

* chore: sync .claude/settings.local.json (accumulated allow-list)

Permissions die Claude Code in de afgelopen sessies heeft gevraagd en
goedgekeurd: extra git-/gh-/npx-commands en MCP-tool-toegang. Single-
machine project, dus committen is acceptabel — bij multi-developer-setup
zou dit bestand juist in .gitignore moeten.
