Address Sourcery review feedback: move face_align and get_one_face
imports from inside per-frame functions to module-level to avoid
repeated attribute lookup overhead in the processing loop.

Fix CoreML execution provider falling back to CPU silently, eliminate
redundant per-frame face detection, and optimize the paste-back blend
to operate on the face bounding box instead of the full frame.
All changes are quality-neutral (pixel-identical output verified) and
benefit non-Mac platforms via the shared detection and paste-back
improvements.
Changes:
- Remove unsupported CoreML options (RequireStaticShapes, MaximumCacheSize)
that caused ORT 1.24 to silently fall back to CPUExecutionProvider
- Add _fast_paste_back(): bbox-restricted erode/blur/blend, skip dead
fake_diff code in insightface's inswapper (computed but never used)
- process_frame() accepts optional pre-detected target_face to avoid
redundant get_one_face() call (~30-40ms saved per frame, all platforms)
- In-memory pipeline detects face once and shares across processors
- Fix get_face_swapper() to fall back to FP16 model when FP32 absent
- Fix pre_start() to accept either model variant (was FP16-only check)
- Make tensorflow import conditional (fixes crash on macOS)
- Add missing tqdm dep, make tensorflow/pygrabber platform-conditional

Some people just want the opencv error gone. I keep on telling them that it is only for blurs and color conversion. It is the onnx runtime who is running the swap.
The macOS Apple Silicon section installed Python 3.11 but then
referenced Python 3.10 in several places:
- `brew install python-tk@3.10` → python-tk@3.11
- Linux comment "Ensure you use the installed Python 3.10" → 3.11
- CoreML section cross-reference "completed the macOS setup above
using Python 3.10" → 3.11
- `python3.10 run.py` usage command → python3.11
- "You must use Python 3.10" note → 3.11
- `brew reinstall python-tk@3.10` troubleshooting tip → 3.11
- Removed `python@3.11` from the list of conflicting versions to
uninstall (it is the required version, not a conflict)
Fixes#1632
The live webcam preview in ui.py calls process_frame_v2() on all
frame processors, but face_enhancer.py was missing this method.
This caused an AttributeError crash when the GFPGAN face enhancer
was enabled during live mode.

Change default face swapper model to FP32 for better GPU compatibility and avoid NaN issues on certain GPUs.
Revamped `run.py` to adjust PATH variables for dependencies setup and re-added with expanded configuration.
Add ToolTip class (modules/ui_tooltip.py) and wire descriptive hover
tooltips onto every button, switch, slider, and dropdown in the main
window. Tooltips appear after a 500ms hover delay and are clamped to
screen bounds.
This requires no new dependencies — ToolTip uses only customtkinter.

cv2_enumerate_cameras(CAP_AVFOUNDATION) probes indices 0-99 through
OpenCV's AVFoundation backend, which intermittently segfaults (exit
code 139) when invalid device indices are probed. Replace with a
bounded cv2.VideoCapture loop (range(10)) that safely skips
unavailable indices.
