Continuum 0.51.0

Continuum 0.51.0

A performance-and-polish release for the chat/transcript surface, plus a Mac-style new-session composer on iOS and a smarter voice trigger.

New & improved

• Smoother transcript scrolling. Fast-scrolling a long session no longer leaves a blank transcript that only reappears after another scroll, and long transcripts stay responsive while a reply streams — without losing your place or your full history. (#660)
• Codex chat parity. Live Codex sessions now render through the same harness path as everything else — edit/diff chips, action-group collapse, "thinking" rows, and full history all behave consistently. (#659)
• Resilient agent sends. A follow-up to a managed agent session whose connection dropped (e.g. after the app restarted) now quietly rebuilds the session and continues, instead of failing with an error. (#657)
• Mac-style new-session composer on iOS. Starting a session on iPhone opens the same centered, keyboard-aware composer as the Mac — native glass model dropdown, repo picker, and dictation — and it shows up inline on the Code tab when a repo has no sessions yet. (#654)
• Left Option for voice. Hold the Left Option key for push-to-talk dictation in the composer (double-tap to latch, tap to stop). (#653)
• Calmer message bubbles. A selected session row and your own message bubbles now draw their border in the same tint as their fill, so they read as one block instead of a highlighted outline. (#658)
• Tooltips stay on screen. Hovering an attachment chip near the screen edge no longer clips its file-path tooltip off the display. (#656)
• Clearer permission toast. Flipping a session to full permissions now shows "Code" in the toast, matching the pill. (#655)
