Remove the pacman hook

Status bars already drop installed entries, and the path unit covers repo
builds, so the hook only ran checkupdates on every transaction.

-A pacman hook also runs update-notify after every pacman transaction, for each logged-in user whose timer is active, so the notification and the status bar file are current right after an upgrade.

-Building into a local repository (`aur build`, `aur sync`) doesn't run pacman, so the hook can't catch it. To run update-notify whenever a repository changes, add the repository files to watch to `update-notify.path`:

+`threshold` is the minimum number of updates (repo + AUR) before update counts are shown. It overrides the `THRESHOLD` setting below for that run's notification only; the pending file keeps the configured value.
+
+`--quiet` updates the pending file without notifying. Changes to a notification already shown are recorded, so the next timer run doesn't repeat them; a new notification is left for the timer. `update-notify.path` uses it (through `update-notify-quiet.service`), so building many packages doesn't notify after each one.
 
 ## Configuration
 
@@ -97,13 +97,13 @@ The content of the last notification is stored in `$XDG_STATE_HOME/update-notify
 Each run also writes the pending updates to `$XDG_STATE_HOME/update-notify/pending`, whether or not the threshold is reached, for status bars such as xmobar to read:
 
 ```
-threshold 30
+threshold <THRESHOLD from the config, not the argument>
 repo <pkg> <newver>
 aur <pkg> <newver>
 kernel <custom-pkg> <stock-ver>

-The file reflects the last run, which the pacman hook and `update-notify.path` keep close to current. To keep a bar current in between, drop entries whose installed version (`pacman -Q`) is no longer older than `newver`, or, for `kernel` lines, whose custom build has caught up with `stock-ver` (ignoring `pkgrel`). This only reads local data, so it's cheap to run often.
