This tool uses the LSP server's Rename method to rename Go symbols
(variables, functions, types, etc.) at a specified position. It supports
both preview mode (dryRun: true, default) and actual application
(dryRun: false) of changes across the workspace.

  • Add renameTool() and renameHandler() to the MCP server
  • Support dryRun parameter: true for preview, false to apply changes
  • Add TestMCPRename to test the tool for both dryRun modes
  • Update MCP instructions with go_rename usage examples for both modes

Fixes golang/go#74887
