[codex] Add semantic search Roam API types

[mdroidian]

Summary

Adds TypeScript coverage for the new Roam semantic search API surface:

• exports SemanticSearchArgs, SemanticSearchHit, and SemanticSearch
• declares window.roamAlphaAPI.data.semanticSearchEnabled()
• declares window.roamAlphaAPI.data.async.semanticSearch(...)

No mock environment defaults are included.

Impact

Extension authors can now call the new async semantic search API with typed arguments and hit records. Callers can use semanticSearchEnabled() before invoking the async API, matching Roam's availability guard contract.

Validation

• npm run build passes
• npm run lint passes with one existing warning in src/types/index.ts
• npm test was previously blocked during test loading by existing missing modules: ../src/backend/getRoamJSUser and react-dom/client

Picked this up from the earlier ready_for_review trigger, but this PR is already merged, so no further review/action is needed.
