Changes checkbox label from "Use Source Format (stream copy)" to "Snippet to Default Format (preserves source quality)". Unchecked state is now "Snippet to Output Format (uses conversion settings)". This clarifies that default format preserves the source file's quality, bitrate, codec, and container without any conversion artifacts.

Updates snippet conversion mode to use configured video/audio codecs, presets, CRF, and bitrates from the Convert tab instead of hardcoded h264/AAC. Output extension now matches selected format (e.g., .mkv, .webm, .mp4). This allows true comparison between source format snippets and conversion preview snippets using user's exact conversion settings.

Implements configurable snippet output mode with two options:
1. Source Format (default): Uses stream copy to preserve exact video/audio quality with source container format. Duration uses keyframe-level precision (may not be frame-perfect).
2. Conversion Format: Re-encodes to h264/AAC MP4 with frame-perfect duration control.
Adds checkbox control in snippet settings UI. Users can now compare source format snippets for merge testing and conversion format snippets for output preview.

Changes snippet generation to always output .mp4 files instead of preserving source extension. This fixes duration accuracy issues caused by container/codec mismatch (e.g., h264 video in .wmv container). MP4 is the proper container for h264-encoded video and ensures FFmpeg respects the -t duration parameter correctly.

Fixed the exit 234 error when generating individual thumbnails by
disabling the timestamp overlay feature which was causing FFmpeg
font-related failures on some systems.
Changes:
- ShowTimestamp: false (was true)
- ShowMetadata: only true for contact sheets (was always true)
The timestamp overlay was causing issues because:
1. DejaVu Sans Mono font might not be available on all systems
2. FFmpeg exits with code 234 when drawtext filter fails
3. Individual thumbnails don't need timestamp overlays anyway
Contact sheets still get metadata headers, which is the main use case
for showing video information on thumbnails.

Changed snippet extraction to use stream copy instead of re-encoding:
- Removed all convert config and encoding logic
- Now uses `-c copy` to copy all streams without re-encoding
- Uses same file extension as source for container compatibility
- Much faster extraction with no quality loss
- Updated job description to indicate "source settings"
This makes snippet generation instant instead of requiring full re-encode.

The progress bar was configured with Max=100 but we were setting
values in the 0.0-1.0 range, causing it to always show ~0%.
Fixed by multiplying the percentage by 100 before setting the value,
so 4/22 = 0.18 becomes 18% instead of 0.18%.
Also fixed SetComplete() to set 100.0 instead of 1.0.

All UI updates from the benchmark goroutine were causing threading
errors because they weren't wrapped in DoFromGoroutine. Fixed:
- UpdateProgress: progress bar and label updates
- AddResult: adding result cards to the display
- SetComplete: final status updates
These methods are called from background goroutines running the
benchmark tests, so all UI updates must be dispatched to the main
thread using fyne.CurrentApp().Driver().DoFromGoroutine().

The issue was that FFmpeg's out_time_ms field is actually in microseconds
(not milliseconds despite the name). We were dividing by 1,000 when we
should have been dividing by 1,000,000 to convert to seconds.
This caused the progress calculation to be off by 1000x, making it
immediately jump to 100% even though the job was just starting.
Also added comprehensive debug logging to track progress samples and
identify calculation issues in the future.

Issue: File list only used half the vertical space, wasting screen real estate.
Changed left panel from VBox to Border layout:
- Top: "Clips to Merge" label and Add/Clear buttons (fixed size)
- Center: File list scroll area (expands to fill remaining space)
The border layout gives the scroll area priority to expand vertically,
maximizing the visible file list area. This is especially important
when merging many clips.

User reports progress jumps to 100% within 10 seconds but merge continues for 45s total.
Added comprehensive debug logging to track:
- Individual clip durations as they're summed
- Total expected duration for the merge
- Exact moment when progress hits 100% with actual vs expected times
- Only update progress when it changes by ≥0.1% (reduces callback spam)
This will help diagnose whether:
- Clip durations are being calculated incorrectly
- FFmpeg's out_time_ms doesn't match expected total duration
- Concat demuxer reports different output duration than sum of inputs

The Merge module's ui.NewDroppable wrappers weren't receiving drop events
because the window-level handleDrop function was intercepting them first.
Added merge module handling to handleDrop function:
- Accepts individual video files and adds them sequentially to merge clips
- Accepts multiple files at once and processes all in order
- Accepts folders and recursively finds all video files
- Probes each video to get duration and metadata
- Sets chapter names defaulting to filename
- Auto-sets output path to "merged.mkv" once 2+ clips are added
- Refreshes UI after each clip is added
Now drag-and-drop works consistently across all modules (Convert, Compare, Inspect, Merge).
