v1.23.0 — protocol visibility in the live TUI

Highlights

• Protocol ribbon on every tab (Ctrl+P): ◆ Ph 2: Cross-Review (R02) · Delivered 1/3 · Waiting: agy, hermes · Next: consensus — with [STALE]/disk-fallback/reconciled-age honesty markers and a 3-line expanded view (Pipeline / Delivery / System).
• Tab activity glyphs: braille spinner (output flowing), · (running silent), ✓ delivered, ✗ failed, x killed, - skipped, ! STALE — fed by tail-cursor growth plus a 2s stat cache for unvisited tabs.
• Narrator lines woven into every transcript (── 12:43:51 codex wrote round-02/codex.md ──) with a bounded replay ring; /narrate cycles protocol → verbose → off.
• Buffered-agent placeholder: a silent agy tab now shows declared buffering, liveness, byte counters, and its own recent activity instead of a blank pane (new buffers_stdout agent flag, TOML-configurable).
• Protocol tab (/protocol or /status): PIPELINE 0-8, DELIVERY matrix, SIGNOFFS, NEXT; /refresh forces a reconcile.
• Home: per-idea phase chip + attention badge.
• Status line: ph=2:xrev-r02 wait=agy,hermes replaces round=….
• Driver: new run.phase event after every phase-changing cursor commit; cursor-save errors are no longer discarded; driver.RebuildDetail exports phase evidence in one disk pass.

All disk reconciliation is event-driven + 15s/60s timers — nothing runs on the 250ms tick; phase never regresses without two agreeing reconciles (virtio-fs discipline).
