Android 0.1.0-beta.7

Descriptive Android notifications and foreground toasts now show the event heading and property/unit context when supplied by an updated MakeReadyOS server. Expanded notifications show the summary; free-form notes and access codes are excluded by the sender. Session binding, opt-in, expiry and duplicate suppression remain enforced. Upgrade the relay before the API, then install the matching Firebase-enabled build. Older senders retain a generic fallback. This public APK is the generic non-Firebase build; operator-specific Firebase APKs and credentials are not included. Bundled web source: 7b9077d. Android version code: 9. Unit tests, lint, builds and signature checks passed; live physical-device delivery of the new summary remains to be confirmed.
