v1.0.5

Video playback fix, durable video storage, and report filtering.

Fixed

Video playback now works in the installed app: the Qt Multimedia FFmpeg
backend DLLs (ffmpeg.dll) are bundled with the executable, so the embedded
player, seek bar, and playback controls are functional on Windows.
Previously the player failed with "영상을 재생할 수 없습니다" because the
frozen app shipped without the media backend.
Reports now cover frames rated 주의 (medium) or higher. 관찰 (low) frames
are omitted from the Markdown, HTML, and PDF report bodies; they remain
available in observations.json.

Videos are now copied into app-managed storage (KorailAnalyzer/videos)
when analysis starts. Playback, analysis, and reports reference the stored
copy, so past records remain viewable even after the original file is
moved or removed (e.g. camera memory cards, USB drives).
Identical videos are stored once: the vault filename is derived from the
file digest, so re-adding the same video does not duplicate storage.

Bundled Ollama and FFmpeg runtimes; no separate Ollama installation is required.
In-app vision model download, hardware recommendation, installation, and selection.
Model-specific prompt harnesses for supported Qwen3-VL and Gemma 4 variants.
