feat: WP-0001 + WP-0002 complete — LEVEL1 core + service interfaces

WP-0001 (Foundation & LEVEL1 Core):
- manifest model (FR-100), MD→DOCX builder (FR-200), DOCX→MD importer
  (FR-300/400), template family registry (FR-600), drift detector (FR-700),
  CLI wiring, pre-commit config, CI skeleton, regression harness

WP-0002 (Service Interfaces & Workflow Orchestration):
- REST service via FastAPI (FR-900): /health, /version, /capabilities,
  /templates, /styles, /validate, /build, /import, /compare,
  /templates/register, /workflows/{name}, /evidence/{run_id}
- Evidence & report store (FR-1400): JSON-backed, per-run, retrievable
  through all interfaces, classification (pass/warnings/failed)
- Composite workflow orchestration (FR-1300): single-file-roundtrip,
  multi-file-roundtrip, release-regression, family-switch-build
- MCP server via FastMCP (FR-1000): all tools + resources
- CLI additions: `markidocx serve`, `markidocx workflow`, `markidocx mcp`
- Interface parity tests: CLI / REST / MCP produce equivalent results

135 tests passing, ruff + mypy clean.
