* chore(deps): allow uv versions below 0.14
* fix(ci): align uv version and generated exports
* fix(dev): check Fedora build headers and AppImage GI bundle
Fail early with distro-specific native dependency hints before dev sync. Verify the AppImage's PyGObject installation and Python path after linuxdeploy, and report isolated GI import failures with actionable path diagnostics. Guard the CI uv pin and cover both preflights with tests.
