feat: 2.14.0 — Eithan terminal toolbar, voice UX, Dross improvements framework

- Terminal renamed Eithan: mobile font A−/A+ (per-URL ttyd opts), same-origin
  xterm Copy/Paste buttons, scroll-to-live, touch-default 17px
- Dross voice: no keyboard pop after transcribe (fine-pointer only focus),
  autogrow textarea to ~5 lines, live amplitude meter on the mic while recording
- Dross improvements: propose_improvement tool (CSS layer, exfil-sanitized,
  owner-approved, per-improvement rollback/restore), public /improvements.css,
  Settings panel. External MCP registry unchanged (no tool leak).
