- Anchor the message list to the bottom (`reverse: true`) so new messages
stay in view instead of landing below the fold.
- Move chat history from the OS keystore (O(n²) JSON blob, silent 200-msg
cap) to a separate encrypted Drift/SQLCipher DB (`ChatDatabase`):
indexed append, uncapped history, dedup as a unique-key invariant. It's
an ephemeral per-device cache, isolated from the inventory schema, its
migrations, and its sync. No data migration (pre-release).
- Add day separators (Today/Yesterday/locale date) and a per-bubble time,
all via ICU (12/24h per locale; Localizations locale maps Asturian →
Spanish for intl date symbols).
- Add peer avatars (deterministic colour from the pubkey + name initial),
surface send failures that were previously silent, and make bubble text
selectable (addresses, links).
- New i18n keys in en/es/pt/ast; tests for grouping, formatting, avatars,
scroll anchoring, storage and send errors.
