Single ffmpeg call per checkpoint instead of ~20 separate calls. Builds
a `select` filter expression for the full frame range and extracts all
sampled frames in one pass with `-vsync vfr`. OCR still short-circuits
on first match.

OCR validation checked a single exact frame number, which broke whenever
Claude Code's UI shifted timing slightly. Now uses a `Checkpoint`
dataclass with frame ranges — scans every 10th frame across a ~200-frame
window and passes if any frame matches. Resilient to normal timing
shifts without losing validation rigor.
Build script now automatically runs TUI demos sequentially (Zellij
conflicts when parallel were the root cause of previous failures), while
non-TUI demos continue running in parallel. Adds per-demo and per-target
timing summaries.

## Summary
- Replace `Ctrl+t`/`Ctrl+n` with Zellij session manager sequences
(`Ctrl+Space` → `tn`/`on`) to avoid Claude Code TUI intercepting
keystrokes
- Remove initial `wt list` — demo now starts directly with the
interactive picker
- Increase marketplace install sleep (5s → 10s) for reliability
- Suppress LSP plugin recommendation dialog via
`lspRecommendationDisabled`
- Update OCR validation checkpoints for new frame timing
## Test plan
- [x] Demo builds successfully (`./docs/demos/build docs --only
wt-zellij-omnibus`)
- [x] OCR validation passes (both frame checkpoints)
- [x] Visual review of key frames confirms no errors

## Summary
- Add interactive picker and copy build caches to home page "Workflow
automation" section
- Update omnibus demo to showcase the picker (TAB 4 uses `wt switch`
with no args, filters to "au", selects auth)
- Fix demo infrastructure: `CLAUDECODE=""` for nested sessions, model →
Opus 4.6, approvals.toml migration, comprehensive tip suppression
## Test plan
- [x] Demo builds and validates (`./docs/demos/build docs --only
wt-zellij-omnibus`)
- [x] Assets published to worktrunk-assets repo
- [x] Doc sync test passes
- [ ] CI green

* Add OCR-based validation for TUI demos
TUI demos (Zellij, interactive UIs) can't be validated via text snapshots because
VHS only captures the outer terminal, not content inside multiplexers. Instead,
extract key frames from GIFs and use OCR (tesseract) to verify expected patterns.
Add `docs/demos/shared/validation.py` with checkpoint definitions and validation
logic. Update build script to validate TUI demos with defined checkpoints during
snapshot mode, skipping those without checkpoints. Document validation approach
in CLAUDE.md with requirements and checkpoint definitions for wt-zellij-omnibus.
* fix(demos): pre-populate Zellij permissions cache to avoid dialog
The zellij-tab-name plugin shows a permission dialog on first run,
which was appearing in recorded demos. Fix by pre-populating the
permissions.kdl cache file before Zellij starts.
Also simplifies the tape by removing the "y" keypress and clear
that were working around the permission dialog.

* fix(demos): re-enable OCR validation checkpoints, handle permission dialog race
The permission dialog timing is non-deterministic (depends on macOS cache state).
Handle both cases:
- If dialog appears: "y" dismisses it
- If no dialog (cache hit): "y" + Enter + clear cleans up the shell
Re-enables validation checkpoints with calibrated frame numbers:
- Frame 100: wt list output with branch table
- Frame 500: Claude UI with Opus indicator
- Frame 2000: Final wt list --full output
