Description

Two new sheet management tools:

• deleteSheet — Deletes a sheet (tab) from a spreadsheet
• renameSheet — Renames a sheet (tab) in a spreadsheet

Motivation

Currently there's no way to delete or rename sheet tabs through the MCP tools. These are basic spreadsheet management operations needed for workflows that involve creating temporary sheets, cleaning up, or reorganizing tabs.

Implementation Details

• Both use spreadsheets.batchUpdate with their respective request types (DeleteSheetRequest, UpdateSheetPropertiesRequest)
• Both require the numeric sheetId (available via getSpreadsheetInfo)
• renameSheet additionally takes newName (string, min length 1)
• Follow existing tool patterns (Zod schemas, getSheetsClient, UserError)
• No changes to helper files — only clients.ts is imported
