Add tool annotations (title, readOnlyHint, destructiveHint) to all 6 MCP tools: Read-only tools (4): - definition: Go to Definition - references: Find References - diagnostics: Get Diagnostics - hover: Hover Information Destructive tools (2): - edit_file: Edit File - rename_symbol: Rename Symbol These annotations help LLMs and clients understand tool behavior and make safer tool selection decisions. Requires mcp-go v0.28.0+ for annotation support. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Adds MCP tool annotations introduced in mcp-go v0.28: a human-readable title plus ReadOnlyHint for the six read-only tools (definition, references, hover, diagnostics, document_symbols, code_actions, semantic_tokens) and DestructiveHint for the two that modify the workspace (edit_file, rename_symbol, format_document). Clients use these to gate auto-approval and surface clearer labels. Adapted from upstream PR isaacphi#107 (bryankthompson) and extended to cover the four extra tools this fork registers.
