feat(P5): Atelier MCP server + vendored Atelier + plugin-registry (REQ-223, REQ-224, REQ-225)
REQ-223: mcp/atelier/server.py plugin-registry MCP server (stdio, D-135).
NovaAtelierServer wraps MCPServer (SDK v2, D-137) if installed; degrades
to _ToolRegistry fallback if SDK absent (testable in CI without SDK).
plugins/principles.py (lookup_principle, list_domains, matrix_lookup) +
plugins/validation.py (validate_against_principles — agentic validation
beyond Wiz/Checkmarx/Mend). 4 tools, 2 plugins.
REQ-224: mcp/atelier/vendor/ pinned Atelier v0.3.6 (D-136) — core/
first-principles, domains/security/first-principles, review/agent-checklist,
matrix/principles-matrix. vendor/VERSION.md + scripts/update_atelier_vendor.sh
for intentional upgrades. mcp/atelier/README.md (tools, architecture,
running, vendoring, extensibility, transport).
REQ-225: tests/test_atelier_mcp.py — 16 tests, all pass. Covers: plugin
discovery (both loaded), 4 tools registered, lookup_security_P4 (+P1,
unknown domain/principle), list_domains (19, security-relevant, ui-ux-not),
matrix_lookup (security 10 P-rules, unknown), validation (good-passes,
bad-secret-fails, bad-swallowed-error-fails, bad-obfuscated-names-fails,
result-structure).
