PY-90755 add in-product uv support survey

Idle in-IDE feedback survey (1-5 star rating + free-form text) shown to PyCharm users working in a uv-managed project, from Aug 1 to Sep 30 2026.

Expose Sdk.isUv as @ApiStatus.Internal so the survey can detect uv interpreters (local and remote); the survey module depends on python community impl.
