Initial MCP serial server implementation

FastMCP server for serial port access via Model Context Protocol:
- 10 tools: list, open, close, read, write, configure, flush, status
- 4 dynamic resources: ports list, data, status, raw hex
- USB device filtering (hides phantom ttyS ports by default)
- Full pyserial support with configurable baudrate/parity/etc
