feat(dankvoice): speak the cloned voices in the TUI (Refs #21)

Every speak-aloud path in the harness gates `--voice` against the bundled
Kokoro enum, so the frank-tts cloned voices could only ever produce files.
`agent/extensions/` auto-loads, so one tracked extension adds the missing
transport: `/say <text>`, `/say on|off` (narrate the final answer at
`agent_end`, silent when the harness schedules a continuation),
`/say voice|voices|stop|status` — OpenAI speech POST plus playback through
pw-play/paplay/ffplay. The endpoint and served id come from the
`api: openai-speech` row of `agent/models.yml`, so the file carries no host
and no secret; markdown is stripped, over-long utterances are cut at a
sentence bound, and the temp WAV dir is always removed.

Verified live in a real TUI session on the workstation (roster
narrator1/narrator2/narrator3; 2.08 s and 1.44 s WAVs played; auto-speak
spoke each finished answer, 1.20 s WAV; unknown voice answers with the
roster). Black-box seam `tests/dankvoice.bats` (12 tests) drives the
extension against a fixture speech endpoint and a stub player.

+## 2026-10-18 — dankvoice: the cloned voices finally speak in the TUI (Refs #21)
+
+Nothing in the harness could pronounce them: the TUI vocalizer and `omp say` gate `--voice` against the bundled Kokoro enum (`omp say --voice narrator1 "test"` → `error: Expected --voice to be one of: af_heart, …`), so frank-tts was reachable only as a file. Added `agent/extensions/dankvoice.ts` — `/say <text>`, `/say on|off` (narrate the final answer at `agent_end`), `/say voice|voices|stop|status` — synthesizing over the OpenAI speech route and playing through `pw-play`/`paplay`/`ffplay`, with the endpoint read from the `api: openai-speech` row of `agent/models.yml` (no host, no secret in the file). Verified live in a real TUI session on the workstation: roster `GET /v1/audio/voices` → `narrator1, narrator2, narrator3`; `/say` produced 99,884 B / 2.08 s and 69,164 B / 1.44 s WAVs handed to the player, temp dirs cleaned afterwards; `/say on` armed the footer (`🔊 narrator1`) and each following finished turn spoke its answer (1.20 s WAV), an unknown voice name answered with the roster instead of speaking, and an `agent_end` carrying `willContinue` (the harness scheduled an auto-retry) is deliberately never narrated. Extension discovery itself proved with a probe file in `~/.omp/agent/extensions/` loaded by a fresh `omp -p` run. Reference page [dankvoice](core/dankvoice.md), registered in the core index; black-box seam `tests/dankvoice.bats` (12 tests).

 ## 2026-10-18 — Noctalia bar layout clobbered by trunk-sync stash, recovered from dangling objects
 
 Frank's months of GUI-built bar customizations (cat/clock/clock-utc/weather start, taskbar center, capsule groups g1–g4, control-cheat-sheet, thickness/font-scale/opacity styling) vanished from the live bar at 16:46. Root cause: the layout existed **only in the working tree** — the repo copy of `settings.toml` carried a stale plain layout because GUI edits hadn't been committed inside the hourly heartbeat window — and a trunk-sync session clearing the dirty tree for `origin/main` stashed it; the stash entry was subsequently destroyed (three `WIP on main` stashes within 60 s, all later dropped). Recovery: `git fsck --lost-found` surfaced the destroyed stash as dangling commit `7fe3ed8` (16:46:09); candidate validated in a sandboxed `XDG_*_HOME` before restore, clobbered file preserved to `.AGENTTRASH/`, layout restored through the symlink target and proven by screenshot, committed as `c87b378` — the durable copy the layout never had. Lessons codified into managed skills: trunk-sync must preservation-**commit** every dirty deployment path (never stash, never `stash clear`), and GUI layout edits get committed the same session they're made.
