[pending-judge] feat(DC-166 r2): MCP tool-set expansion + workflows double-prefix route fix (17 -> 28 tools)

Owner directive "Do it" (2026-10-09): expand the MCP tool set so the
"manage your entire infrastructure" claim is true of the product. 11 new
tools over EXISTING routes: calendar (events/add_source), security
(events/summary), license_status, capabilities, DNS add/remove record,
deploy_recipe, run_workflow, tailscale_status. Handlers verified against
the actual route declarations; credential TYPE passthrough and the DC-162
machine-only tools/call gate unchanged (tests included).

judge r1 (grade C, urn:ump:fyvivcvrphjm5wk227ujr2yzfcgcdvwekjmw6lvnqvjosqrjhtbq)
blocking issues — all fixed in this revision:
1. WORKFLOWS DOUBLE-PREFIX (real product bug the judge caught):
   routes/workflows.js declared literal '/workflows/...' paths while
   src/app.js mounts the router at /workflows — composed path was
   /api/v1/workflows/workflows/..., which the SHIPPED dashboard bundle
   (status/js/bundled-workflows.js calls single-prefix /api/v1/workflows/)
   never hits: the workflows UI has been broken in production. Fixed by
   making route paths RELATIVE to the mount (same class as the recipes
   fix); run-workflow MCP path now matches. Also reordered /history
   before /:workflowId/history so the literal segment is not captured as
   an id (limit 100 vs 50 asserted in tests).
2. Verifier substring check replaced: NEW integration suite
   (__tests__/mcp/mcp-core-dc166-integration.test.js) resolves EVERY MCP
   tool call's complete mounted (method, path) against the declared route
   patterns extracted from the owning route file (params matched as
   patterns, comments excluded) — a double prefix or wrong method fails
   the run. Plus real-composition dispatch through the actual workflows
   router: POST /api/v1/workflows/:id/run reaches the run handler
   (sentinel '"ran":true'), list/history handlers land correctly, and a
   static guard fails any route file that re-declares its own mount name.
3. Both verbatim-command claims in the brief now name their file.

polish applied: calendar window-math test bounds tightened to exactly
~7 days (was a weak 6-hour lower bound); extra blank line before
tools/list removed; calendar_add_source schema gained the token property
the route already accepts (schema now matches the documented API).

Tests: 73 prior + 15 dc166 unit + 6 integration = 94 MCP tests green;
full suite 6 failed + 3697 passed == 3703 total (known-red billing
family, band-guarded; base-proof shows the same 6 red at a1b8fa3).
eslint: 0 errors on touched files (warnings count unchanged vs base).
