* Bound clipboard capture reads
* Bound the watched clipboard read and drop copies cut off at the deadline
In watch mode capture.sh reads the copy from the owner's pipe on stdin, to EOF, with no bound. An owner that stalls without closing its end keeps the callback alive, and wl-paste --watch handles no further clipboard events until it exits. That matches #9443, whose stuck capture.sh had no wl-paste child: --list-types never reads from the owner.
Every read now goes through one bounded reader into a temporary file, and the copy is recorded only when the read finished, so a snapshot that stalls halfway no longer records its first half.
