feat: add host-specific CLI arguments for MCP configure command

- Add --timeout argument for Gemini (request timeout in milliseconds)
- Add --trust argument for Gemini (bypass tool call confirmations)
- Add --cwd argument for Gemini (working directory for stdio transport)
- Add --env-file argument for Cursor/VS Code/LM Studio (path to environment file)

Implementation details:
- Updated handle_mcp_configure() signature with 4 new parameters
- Added host-specific argument validation (error if used with incompatible hosts)
- Integrated new fields into MCPServerConfigOmni creation
- Updated argument parser with new CLI flags
- Updated main() function call to pass new parameters

Testing:
- Created test_mcp_cli_host_specific_args.py with 12 comprehensive tests
- Updated test_mcp_cli_direct_management.py to match new function signature
- All 260 MCP tests passing (100% success rate)

This implements Phase 2 of the original design specifications for commonly-used
host-specific fields across Gemini, Cursor, and VS Code hosts.
