Save Tool v1.8.2 - Threads share links now download

Fixed: Threads share links did not download

The Threads app's "Copy link" gives a share link like threads.com/share/BAVzxB05HF/, not a post link. Save Tool only understood threads.com/@user/post/<code>, so it failed with "url is not a post link" and yt-dlp has no Threads support to fall back on.

Now a share link is resolved first (Threads redirects it to the real post) and then downloaded normally. Verified with the exact link that failed:

input:  https://www.threads.com/share/BAVzxB05HF/
result: threads_DeiR8J_kpfn.mp4  (status: Saved)

Also: long URLs inside error messages are shortened to the host name, and error text is clamped to 5 lines on the card (full text on hover / long-press) so one bad link no longer blows up the page.

Recommended download: SaveTool-v1.8.2-win64.zip - everything included, unzip and double-click savetoolw.exe.
