feat(FN-3189): add explicit slow-lane CI gating and inline priority picker

Merges FN-3183/FN-3186 (priority picker in quick-entry box) and FN-3189 (CLI slow-lane test gating and CI lane) into the codebase. The quick-entry box gains inline priority selection, while the test suite introduces explicit slow/pre-release lane classification and a corresponding CI gate in the wor
