Greptile Summary

This PR adds sheet selector functionality for Google Sheets and Microsoft Excel tools, enabling users to select specific sheets/tabs within spreadsheets through a dropdown interface. The implementation introduces:

Key Changes:

• New sheet-selector SubBlockType for selecting sheets/tabs within spreadsheets
• Two new API routes (/api/tools/google_sheets/sheets and /api/tools/microsoft_excel/sheets) to fetch available sheets
• New selector definitions (google.sheets and microsoft.excel.sheets) in the selector registry
• V2 versions of Google Sheets and Microsoft Excel blocks with explicit sheet name parameters
• V2 tool implementations (read, write, update, append) that accept sheetName as a required parameter
• Updated documentation reflecting the new sheet selection capabilities

Architecture:
The implementation follows established patterns in the codebase, mirroring existing selector types (file-selector, folder-selector, etc.). The sheet selector depends on both credential and spreadsheet ID being selected first, fetches available sheets via API routes with proper OAuth authentication, and presents them in a searchable combobox.

Testing:
According to the PR description, the changes were tested manually. The implementation is consistent with existing selector patterns that are already in production.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The implementation follows consistent architectural patterns established in the codebase, properly handles authentication and authorization, includes appropriate error handling, and integrates cleanly with existing selector infrastructure. The changes are additive (V2 versions) rather than modifying existing functionality, reducing regression risk. Code quality is high with proper TypeScript typing, logging, and edge case handling.
• No files require special attention
