Subject: feat(mcp): add tool discovery and per-tool permissions

- Add MCP protocol client for tool discovery (initialize + tools/list)
- Show discovered tools in settings UI with enable/disable checkboxes
- Build explicit allowedTools list from enabled MCP tools
- Remove bypassPermissions hack - now uses proper tool allowlisting
- Format: mcp__servername__toolname for SDK allowedTools
