v0.4.4 — UI/UX polish

- Long lines in code blocks and diffs now scroll horizontally instead of being cut off
- Clear feedback when a message fails to send — no more silently dropped messages
- Biometric unlock no longer auto-prompts unexpectedly, and cancelling is handled cleanly
- Session delete and rename now show an error if they fail, and guard against double-taps
- Fixed a pull-to-refresh spinner that could hang
- Server URL is validated when you add or edit a connection
