On QNAP, /usr/local/bin is a tiny RAM disk. The installer was downloading
the binary then mv'ing it there, which failed when the RAM disk was full.
The QNAP-specific logic that copies to the persistent data volume only
ran after that mv.
Move QNAP detection before the download step so INSTALL_DIR points to the
persistent data volume (e.g. /share/CACHEDEV1_DATA/.pulse-agent) directly.
The wrapper script still attempts to copy to /usr/local/bin at boot but
falls back to running from persistent storage if that fails.
Also fixes:
- pkill -f pattern in wrapper could match and kill the wrapper itself
(path contains "pulse-agent"); switched to pkill -x for exact match
- Upgrade detection now checks /usr/local/bin for legacy QNAP installs
- Uninstall cleans up /usr/local/bin runtime copy
