Bump version to v0.1.8 — Windows playtest fixes

- Fix switchAccount: check signer was set after loginWithNsec before
  returning; fall back to loginWithPubkey on silent failure; always
  navigate to feed after switch to clear stale UI
- Fix profile edit button: hidden in read-only (npub) mode; read-only
  badge shown in profile header to make state visible
- Sidebar: show version number (v0.1.8) below WRYSTR brand, auto-tracked
  from package.json — no more hardcoding
- Support page: increase QR code gap (gap-8 → gap-16) to prevent
  accidentally scanning the wrong address
- ROADMAP: add language/alphabet feed filter to Phase 3 backlog
