fix(notion): resolve custom page title properties

[BillLeoutsakosvl346]

Summary

• resolve Notion page titles by property type instead of a literal property key
• preserve legacy and V2 response shapes and the existing Untitled fallback
• cover custom-title selector hydration and all six read/create/update response transforms

Automated validation

• bun run test -- lib/selectors/server/providers/notion.test.ts tools/notion/responses.test.ts
• bunx biome check lib/selectors/server/providers/notion.test.ts tools/notion/read.ts tools/notion/create_page.ts tools/notion/update_page.ts tools/notion/responses.test.ts
• bun run type-check
• bun run check:api-validation

All checks passed.

Browser validation

Using a disposable Notion database whose primary title property was renamed to Project:

• the page selector listed Sim Custom Title Row
• saving and reloading the workflow hydrated the same selector label through the detail request
• a Notion Read execution returned Sim Custom Title Row as its title
• selector list and detail requests returned 200, with no related browser-console or server-log errors and no credentials exposed

The browser tooling did not expose the raw response body directly; normalized label behavior was verified through the rendered selector state, successful list/detail request logs, and focused adapter coverage.

Greptile Summary

This PR updates all six Notion read, create, and update response transforms to resolve page titles by the property's title type rather than a literal property key, while preserving the Untitled fallback.

• Reuses the shared extractTitle helper across legacy and V2 response adapters.
• Adds table-driven coverage for custom-named title properties.
• Updates selector coverage to use a renamed primary title property.

Confidence Score: 5/5

The PR appears safe to merge with no actionable correctness, security, or compatibility issues identified.

The shared extractor locates Notion’s single title-typed page property regardless of its user-defined name, preserves empty-title fallback behavior, and is applied consistently across legacy and V2 transforms.
