feat: add SolidTime MCP server for time tracking integration

Implements a Model Context Protocol server that exposes SolidTime's
time tracking API as 22+ tools for use with Claude, Cursor, and other
MCP-compatible clients. Supports stdio and HTTP transport modes,
Docker deployment, and self-hosted SolidTime instances.
