LF normalization across OSes; *.sql pinned to LF for stable diffs.
Tests cover the rational frame-rate parser (NTSC 29.97, integer fps,
slow-mo 240, ffprobe's 0/0 unknown sentinel, malformed and out-of-range
inputs). Extracted the closure into a free fn for the test seam.

Adds frame_rate to GenerateVideoResponse so the mobile scrubber can step
at the source's real fps instead of a hardcoded 30. probe_video_stream_meta
gains a frame_rate field (avg_frame_rate preferred, r_frame_rate fallback,
nonsense values rejected) and is now pub so the handler can reuse it.
Cost is one ffprobe per /video/generate call; degrades silently to None
on probe failure.
