fix: VideoInfo.fps returns float instead of truncated int (#2210) 
* VideoInfo.fps returns float instead of int

Truncating the raw CAP_PROP_FPS value with int() causes timing drift for
non-integer frame rates (23.976, 29.97, 59.94). Over a long video this
accumulates into noticeable sync errors — e.g. 23 vs 23.976 drifts ~1s
per minute of footage.

Changes:
- VideoInfo.fps type annotation: int -> float
- from_video_path: int(video.get(CAP_PROP_FPS)) -> float(...)
- ByteTrack.frame_rate type annotation: int -> float (already converts
  to int internally via max_time_lost = int(frame_rate / 30.0 * buffer))
- Tests: assert fps is float, add float_fps_video_path fixture at 23.976

* fix: update examples to cast float fps to int where required
* fix: wrap long docstring line in FPSBasedTimer (ruff E501)
* test: remove unused float_fps_video_path fixture
