Switch update script to Seerr

The migration wrote the new update script directly to /usr/bin/update
while the parent shell still had the file open for reading. Since the
new content (with shebang) is longer than the original single-line file,
bash would read leftover bytes from the new content after the child
process exited, causing:
  /usr/bin/update: line 2: syntax error near unexpected token )'

Fix: write to a temp file first, then mv over /usr/bin/update. This
replaces the inode so the parent shell's fd sees EOF on the old
(unlinked) inode instead of reading into the new content.
