v0.1.8

Failure modes, mostly. The kind that leave you with a file you think is fine.

• A failed, cancelled, or interrupted encode no longer leaves a half-written video at the output path. It writes a hidden .part file next to the destination and only renames it once FFmpeg exits cleanly
• Ctrl+C stops the running FFmpeg instead of leaving it behind, and prints cancelled with exit code 130
• The local web app has a Cancel button, and closing the tab stops the encode after a ten-second grace period instead of letting FFmpeg run to completion
• The web app can switch the player between the original and the compressed file, and warns when the browser cannot decode H.265
• The web app retires the oldest uploads past the tenth, so a tab left open all day does not fill the temp directory
• Replacing an output that another program has open now fails with a clear message and keeps the finished file, instead of deleting it
• The version now comes from package.json alone. scripts/bump-site.mjs syncs the site and READMEs, and a test fails if they drift
• The local app refuses a text file, an image, or an empty file with a readable message, instead of accepting it and failing later with a path to ffprobe
• Uploaded file names are reduced to a bare file name, so nothing like ../../evil.mp4 can reach the download header
• Malformed request bodies return 400 instead of 500, and impossible byte ranges return 416 instead of a broken stream
• Both the CLI and the web app now say when tracks are dropped: extra audio tracks, subtitles, surround audio downmixed to stereo, and frame rates above 60 fps
• --out refuses to overwrite the input file, and --crf, --preset, --codec, and --port are validated before encoding starts
• Low-frame-rate sources are left alone. A 5 fps timelapse used to be forced up to 10 fps, which duplicated frames and inflated the bitrate the planner assumed
