fix(mcp): auto-register tools on startup and support cross-platform setup for all major AI IDEs

- Fix missing mcp_server.tools import on server initialization so mobile_run_task, mobile_manage_task, mobile_get_device_state, and mobile_inspect_trace are automatically registered.

- Inject PYTHONPATH in generated and installed MCP configurations to guarantee Python module resolution across Windows, macOS, and Linux regardless of IDE CWD.

- Expand artemis mcp --install and --generate-config to support VS Code, Cline, Roo Code, Claude Code CLI (~/.claude.json), Cursor, Windsurf, Antigravity, and OpenClaw.

- Enhance config file merging with robust exception handling and fallback initialization.
