v1.7.3 — visual master/variant distinction, page-title filenames

✨ New in this release

• Master vs. variant badges — the HLS master row (cdndirector) now has a bright badge with a gold outline; per‑track audio‑only and video‑only variant rows are muted with a tooltip warning, so you grab the right thing at a glance.
• Page‑title filenames — Grab now names output files after the browser tab title instead of mediasniff_timestamp.mp4 (when a title is available).
• Filtered list — individual .m4s/.ts/init segments and ad/cookie‑sync URLs are filtered out, leaving only the real manifests.
• #fragment fix — manifest URLs ending in now route correctly to N_m3u8DL-RE.
• Collision‑safe outputs — concurrent Grabs never race on the output filename.
