- Added image loading from HTTP and HTTPS URLs with descriptive URL validation errors
- Added optional caching for image URL loads using the shared Supervision cache
- Improved URL downloads with atomic file replacement and shared download behavior across image loading and asset downloads
- Updated image decoding compatibility with Pillow fallbacks when OpenCV decoding or encoding is unavailable

- Remove unused compatibility operations and use focused Pillow and NumPy paths to reduce maintained fallback code.
- Preserve numerical decisions and hot-path performance with exact regression coverage and bounded algorithms.
- Preserve INTER_LINEAR uint8 reductions within one LSB while retaining the resize performance budget and numeric RGBA handling.
- Restore repeated-endpoint contour anchors and bound cross-platform chamfer coefficient drift in regression tests.

_get_text_size approximated thickness-to-stroke padding with
thickness // 2 formulas that diverge from the thickness - 1
stroke_width _put_text actually renders with. Past thickness 2 the
padding grows too slowly, so heavy-stroke descender pixels can fall
outside the reported box, breaking the documented enclosure
guarantee. Both functions now derive stroke_width from one shared
helper.

Text fallback now renders through Pillow with the DejaVu Sans face
resolved via matplotlib font_manager, replacing the Hershey stroke-font
reader; getTextSize metrics derive from the same font and differ from
OpenCV within the documented visual-divergence tier.
Remove the packaged Hershey glyph data (hershey_fonts.json, provenance,
license) and its _cv2/data package-data entry.
Delete unused fallbacks: _geometry _fill_poly and _point_in_polygon
(live fillPoly is the Pillow one in _drawing) and _common _unavailable.
Replace test_hershey with Pillow-oriented test_text, drop test_common,
and point test_contours/test_geometry at _drawing._fill_poly. Document
the fallback text-backend change in the changelog.

- Add the PyAV-backed file-video and audio fallback to the compatibility layer.
- Declare PyAV alongside OpenCV until the final dependency-removal integration.
- _VideoWriter now rejects is_color=False (NotImplementedError) instead of
silently dropping it, since the PyAV fallback only encodes 3-channel frames.
- _mux_audio cleanup (container closes, temp-file removal) is now best-effort
so a failing close/remove in finally can no longer mask the primary result
or the original exception.
- The subprocess used to validate the cv2-free fallback had no timeout;
a hang (import deadlock, codec probe stall) could block the whole CI
run. Added a 60s timeout so a hang fails fast with a clear traceback
instead of an opaque suite-wide stall.
- process_video(preserve_audio=True) docstring still described the old
ffmpeg-based muxing; audio remuxing was reimplemented with PyAV and no
longer requires an external ffmpeg executable.
- get_video_frames_generator's documented webcam fallback
(`_cv2.VideoCapture(0)`) silently fails under the PyAV backend: the
BackendUnavailableError raised for integer sources was swallowed with no
logging, so isOpened() just returns False with zero diagnostic signal.
Doc note now states the limitation explicitly and the capture logs a
warning instead of failing silently.
