v0.2.2 — namespaced plugin id

Breaking (plugin id): the Quickshell plugin id is now io.github.mrcode.prayer-times, namespaced ahead of the marketplace listing that would have made the old bare prayer.times permanent.

Existing installs migrate automatically — omarchy-prayer setup moves the plugin directory and rewrites the shell's plugin list. The shell keys plugins on the manifest id rather than the directory name, so a stale manifest in a renamed directory would silently break the widget; setup now warns if it detects that mismatch.

Also fixed: a missing CLI is now detected by a start watchdog. Quickshell does not emit onExited when a binary is absent — it only logs "Process failed to start" — so without this the widget sat on an empty pill forever. It now says omarchy-prayer is not installed — run: yay -S omarchy-prayer.
