1.5.0

Signed device IPA, auto-published (e1981c9). Signed with a free-tier Apple ID cert/profile — install directly via LiveContainer/AltStore/SideStore (no resigning needed), but the cert expires after 7 days and the profile is locked to registered device UDIDs. No push notifications (free Apple ID can't get that entitlement).

Milestone release: full plugin system with real hooks — on_send (modify outgoing text), on_receive (react to incoming messages, including local-only message hiding without blocking), a real host API (clipboard, haptics, sounds, dialogs, persistent per-plugin settings), and settings screens with buttons/selectors/text inputs. 27 example plugins included.

Full Changelog: 0.3.14...1.5.0
