Changed
- Options page — dropped the dedicated "Colab Notebook" nav tab/section; the script list now lives in README.md and renders through the existing Help/README tab, avoiding duplication.
- README — added a "Helpful Scripts" section with links to each companion script/notebook and a usage disclaimer.

• hls-colab.ipynb — some captured exports log the same progressive-file URL once per HTTP range-request during playback instead of real HLS chunks. Feeding that list straight into the parallel downloader made every worker pull the full file body into memory at once (WORKERS × file size), crashing the Colab session. Segment lists are now deduped before download; a single surviving URL routes to a direct download instead of the chunked pipeline.
• hls-colab.ipynb download_all / retry_failed — segment bodies are now streamed straight to disk instead of buffered fully in memory (r.content), hardening the same code path for legitimately large real HLS segments.

• src/scripts/dl-tubi.sh — local (non-Colab) downloader for the duplicate-URL case: dedupe + single resumable curl download.
