bvandeusen 4d6bae77b4 feat(mcp): project + milestone CRUD tools
Seven tools matching existing fable-mcp contracts:
  - fable_list/get/create/update_project (no delete; archive via status)
  - fable_list/create/update_milestone (no get; no delete)

LLM-era similarity-check / 'confirmed' guard for create_project is
NOT replicated — Claude doesn't need it. The service's auto-summary
regeneration side effect (services.projects.update_project) stays
for now; gets removed in Phase 7 along with all other LLM code.

Notable sentinels:
  - update_milestone: order_index=-1 means "leave unchanged" (0 is valid)
  - create_milestone: description="" becomes None at the service layer

"""Milestone CRUD MCP tools — thin wrappers over services/milestones.py.
Mirrors existing fable-mcp milestone tool contracts: list/create/update. The
existing surface has no fable_get_milestone or fable_delete_milestone — kept
that way for parity.
Sentinels:
- title="" / description="" / status="" → "leave unchanged" on update
- order_index=-1 → "leave unchanged" on update (0 is a valid order_index)
- status="active" default on create
