fix: Hardcode DB config and start server before DB connection

- db.ts: Hardcode 10.0.1.1 (infra VM) to prevent env var issues
- index.ts: Start MCP server before DB connection (fixes Claude Code timing)
- run.sh/run.js: Add wrapper scripts with embedded env vars
- start.sh: Update with correct WireGuard config

Fixes task-mcp failing to connect in Claude Code sessions after
WireGuard migration. The server must respond to MCP initialize
before stdin closes, which requires starting before slow DB ops.
