More improvements to EffectBase support of masks (allowing all effects to use animated masks better).
...
- Mask: Start/End (seconds) picks the exact part of a mask video to use.
- Time Mode: Timeline follows project timing; Source FPS follows mask file timing.
- Loop mode then defines playback behavior: Play Once, Repeat, or Ping-Pong.

Integrating Mask effect with invert mask property and unit tests. This allows the Mask effect to invert the mask easily.

- Added a new common mask_reader feature at EffectBase, so all video effects can be mask-limited automatically (audio effects ignore it).
...
- Added optional Mask Mode overrides for Blur, Saturation, Brightness, Hue, Pixelate, and Sharpen (Limit to Mask, Vary Strength).
- Kept unified mask property naming (mask_reader) with legacy JSON compatibility where needed.
- Added/updated unit tests for base mask behavior, per-effect mode behavior, and JSON round-trips.
- Fixed profile tests to write generated files into the build/test directory instead of the source examples/ folder.

- Fix FFmpegReader first-frame black regression by anchoring PTS offset to video start (and correcting video offset to use packet PTS), so AAC preroll/skip-samples no longer shifts frame 1.
...
- Add examples/test_aac_preroll.mp4 fixture (small, deterministic AAC-preroll sample) for reproducing and testing the regression.

• - Fix VideoCacheThread::isReady() so preroll readiness is clamped by frames actually available to the timeline boundary (end/start), preventing playback from stalling in PLAY near the end.
...
- Add regression coverage in tests/VideoCacheThread.cpp (isReady: clamps preroll requirement at timeline boundaries) for forward-near-end and backward-near-start cases.

Harden playback/cache path for malformed media and concurrent timeline updates
...
- Invalidate timeline cache on ApplyJsonDiff() clip insert (remove affected frame range).
- Add lock in Timeline::ClearAllCache() for safe concurrent access.
- Make VideoCacheThread cross-thread state safe (atomics + seek-state mutex).
- Lock CacheMemory::Contains() to avoid races.
- Handle malformed audio streams in FFmpegReader by disabling invalid audio and continuing video-only.
- Add FPS/timebase safety fallbacks in FFmpeg frame/PTS math.
- Guard Frame::GetSamplesPerFrame() against invalid inputs.
- Add/adjust regression tests for cache invalidation and invalid rate handling.

FFmpegReader: add duration strategy modes and unify duration/frame calculations. This is a potentially breaking change, where we ensure all durations and video_length calculations coming from FFmpegReader are now fully consistent - even if we must slightly adjust a duration from the video or audio stream. This keeps the 2 attributes identical in meaning (video_length X FPS == duration, no exceptions). Unknown durations are no longer -1 video_length but 0, and 0 duration.

Fixing regression inside AudioWaveformer so it uses a proper detached reader, and no longer mutates the Clip's reader (preventing a bug which caused our video to disappear when waveforms were used on the clip)

Refactoring the AudioWaveformer again, this time to de-couple it from the actual clip object passed to it, and to no longer iterate over the potential longer time keyframes using GetFrame alone. Now, we only decode audio-streams, and only get the original samples (reduced sample rate drastically), and finally we apply keyframes (volume and time) to modify our original samples. This is a HUGE speed-up boost for waveform generation.

Fixing AudioWaveformer::ExtractSamples to pause temporarily when a clip's reader is closed, and resume extracting when it's open again. This prevents a very common crash / bug when generating waveforms for longer audio clips and continuing to make chagnes on the timeline (which closes all clips temporarily - interrupting the waveform extracting).

Improving audio directionality, with new function: SetAudioDirection(), so we can safely flip audio buffer direction when needed (i.e. time curves, reversed time). Also adding a new SetDirectionHint function to FrameMapper class - so our Clip class can inform the FrameMapper of its direction at any given moment. Also, clear resampler when changing directions inside a Time curve (since the audio buffer will be flipped - the resampler internal cache must be cleared).
