fix: [AI-0000] relax mcp pin to >=1.9.0,<2.0.0 (release 0.3.1) (#103)

The `mcp~=1.9.0` cap (`<1.10.0`) blocks downstream consumers from using
newer `mcp` releases required by `claude-agent-sdk` 0.2.x. datapilot only
uses the stable mcp client API (`ClientSession`, `StdioServerParameters`,
`stdio_client`), which is unchanged across `mcp` 1.x, so the upper cap is
unnecessary.

- Relax `mcp` pin from `~=1.9.0` to `>=1.9.0,<2.0.0`
- Bump version `0.3.0` -> `0.3.1` across bump2version-tracked files
- Add CHANGELOG entry
