lacma-2026 demo: fresh capture from macOS ac-native, includes prompt

Ran .claude/worktrees/nervous-newton-134547/fedac/native/macos/scripts/demo.sh
with WALTZ=viennese to capture a brand-new 15.77s MKV from the macOS
ac-native build. Script:

- Injects a "notepat<enter>" keystroke sequence into the prompt
- Captures framebuffer → PNG frames + the CoreAudio synth tap → WAV
- Generates `say -v Samantha` TTS greeting synced to f==10 of boot
- Muxes everything into one MKV with sample-aligned audio

Fresh video structure:
0:00 – 2:00 boot animation with "hi @jeffrey, enjoy Los Angeles!" TTS
2:00 – 3:70 prompt piece with live typing "notepat" + autocomplete
3:70 – 5:00 notepat loading
5:00 – 15:77 notepat playing the Viennese waltz drum pattern
15:77 – 17:28 shutdown strobe (simulated, matches C code exactly)

Narration retimed for this 17.28s sequence, still constrained to not
talk over the boot TTS or the shutdown audio slot. Cue [0:02.5] now
lands on the prompt during "notepat" typing, calling it out directly.

Audio fix from the previous commit (concat filter + aresample + async)
carried forward — no drift between the fresh demo and the shutdown
strobe at the boundary.

Caption chip + byline updated: sequence now includes "prompt" and
"type 'notepat'" steps that are actually visible in the capture.

Cachebuster v=5 → v=6.
