[Feature] Community verification of MCP config snippets across clients

### Problem

Split from #32.

PR #57 added config snippets for 13 MCP clients. Only VS Code was verified on a real machine (macOS — MCP server discovered, 4 tools listed). The other 12 clients have format verified against official docs but were not tested with the actual client software. Some snippets may have subtle format issues that only surface when the client tries to load them.

### Proposed solution

Community verification effort. If you use any of these clients, please help verify:

1. Follow the snippet in mcp-integration.md for your client
2. Start the client and verify the Hebb Mind MCP server appears
3. Confirm the 4 tools are discoverable: write_memory, search_memory, consolidate, ingest_conversation
4. Comment on this issue with: client name, OS, "verified" or "broken + details"

Clients needing verification:
- Amp, Claude Desktop, Cline, Copilot (VS Code), Cursor, Gemini CLI, Goose, Kiro, LM Studio, opencode, Warp, Windsurf

Any broken snippets will be fixed in mcp-integration.md (EN + zh).

### Alternatives considered

Install all 12 clients on one machine and test. Not practical — some are paid, platform-specific, or require specific IDE setups.
