KithMoot 0.6.117: account authentication for room relays

Install over your existing KithMoot app to keep your account and rooms.

1. Leave open rooms, then open Settings → Connections → Nostr relays.
2. Save and enable the relay, choose Use signed-in account, check the URL and account npub, and confirm.
3. Reopen the room and approve authentication in your signer. Send a fresh test message; retry earlier refused sends afterwards.

Permission lasts for the current account session on the exact relay. Sign-out, account replacement, app restart or removing/disabling the relay clears it. Anonymous rooms, discovery and background listeners gain no new identity permission. The relay must support device-signed writes from an authenticated allowlisted account.

Linux desktop already offers the control in the room’s relay settings.

This production-signed APK passed all 17 qualification jobs, signature/lineage checks and an emulator upgrade preserving app data. Real sender delivery and physical GrapheneOS acceptance remain pending. Source: c72c69e3d182919662c185d2399130ab7e932ee4; later camera-startup changes in PR #343 are outside this binary.
