Mcp undefined filename bug (#718)

* fix(mcp): Use fileName.text as fallback when webUrl is undefined for local repos

For local repositories, the webUrl field is undefined since there's no
web hosting URL. This fix makes both search_code and list_repos tools
fallback to the fileName.text and repoCloneUrl respectively when webUrl
is not available.

* fix fields and changelog

* Move MCP changelog entry to MCP package changelog

Moved the changelog entry for PR #718 from the main CHANGELOG.md to
packages/mcp/CHANGELOG.md as requested.
