feat(search): add Lucidchart and Lucidspark live search

[waleedlatif1]

Summary

• Add Lucidchart and Lucidspark live search through Lucid’s official read-only MCP server, using the existing member-account connection and authorization flow.
• Support title discovery, document-scoped shape-text search and complete structured graph reads with identity, revision, coverage and size checks. Document the search limits and include Lucid’s official SVG icon.
• Preserve existing MCP payload handling while recognizing Lucid’s widget metadata envelope. Allow only the four required read tools.

Companion: simstudioai/mothership#556

Type of Change

• New feature

Testing

• Real Lucidchart and Lucidspark MCP acceptance: 12 positive/negative query and read checks; outgoing arguments validated against advertised schemas.
• Real loopback HTTP MCP suite: 31 checks with JSON reports, including multi-page/region preservation, limits, cancellation and access/revision changes. Guard-removal controls and regressions independently proved query admission, candidate isolation, error preservation and complete-read safety.
• 13 real Postgres setup checks; 1,127 provider/credential/MCP regressions and 10 contract tests.
• All 26 workspace type checks, 52 audits, lint, applicable generators, registry and docs checks passed. Cleanup and test-audit completed.
• Live samples cover one page/region per product; larger layouts use synthetic HTTP fixtures. The local Sim browser enrollment and LLM flow remain unverified because of a session-recovery loop; no authentication bypass was used.

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

•  Lucid scopes reject every result apps/sim/lib/sim-search/live/policy-schema.ts:107 ▶

  When an administrator selects specific Lucid documents or excludes document IDs, search returns no results-even for documents the policy allows. These settings require each candidate to be verified, but the verifier has no Lucid case and rejects them all. Add Lucid document-ID verification so the new Documents scope works.
