push-notifications

# Push notifications The plugin notifies when a thread asks a question, finishes a turn, or stops on an error. Mobile devices receive Expo push messages even when the app is closed. Web and desktop clients receive system notifications only while a bb tab or app window stays open, and each browser grants permission separately in the plugin settings. ```sh bb push-notifications status [--json] bb push-notifications list [--json] bb push-notifications add --token <expo-push-token> --platform <ios|android> --label <device-name> [--json] bb push-notifications remove <id> [--json] bb push-notifications test <web|desktop> [--json] bb push-notifications thread <thread> [--level inherit|all|input-only|muted] bb plugin config push-notifications set <mobileEnabled|webEnabled|desktopEnabled> <true|false> bb plugin config push-notifications set defaultLevel <all|input-only|muted> bb plugin config push-notifications set childLevel <inherit|all|input-only|muted> bb plugin config push-notifications set expoPushUrl <url> ``` - `add` upserts by token: a known token refreshes its label and last-seen time and keeps its id. Expo tokens that are no longer registered are removed after a failed delivery. - `list` shows token suffixes only. - The three channel switches default to `true` and apply immediately to this server. `bb plugin disable push-notifications` stops all delivery. - `test` broadcasts to every connected, permitted client of that type and fails when the channel is disabled. Success confirms the broadcast, not that the OS showed a banner; system notification settings can still suppress it. - `thread` prints a thread's resolved notification level and its source; `--level` sets the thread's own level. A thread uses its own level, else `childLevel` if it has a parent (default `input-only`; `inherit` follows `defaultLevel`), else `defaultLevel` (default `all`). Every ancestor's own level also caps its child threads. `all` notifies on finished turns too, `input-only` keeps questions, approvals, and errors only, and `muted` sends nothing. Inspect `status` before changing a channel, and change only the requested channel or device.
