Refactor internal-cli bin.ts into separate command files

## Problem Statement The internal CLI `bin.ts` file is ~1200 lines long, making it difficult to navigate. All 23 commands, their schemas, error classes, and utility functions are in a single file. ## Solution Extract each command into its own file in a `commands/` folder. The `bin.ts` becomes a thin orchestration file that imports and registers commands. ## Implementation Plan ### Phase 1: Create shared infrastructure 1. Create `src/shared/main-layer.ts` - extract `MainLayerLive` layer (merge of `AppLayerLive` and `OpenTelemetryLive`) 2. Create `src/shared/schemas.ts` - extract `clipsSchema` (shared between `create-video-from-clips` and `send-clips-to-davinci-resolve`) 3. Update `bin.ts` to import from these new files, verify build passes ### Phase 2: Extract commands (one commit per command) Each command file exports a `register(program: Command)` function. Extract in this order: 4. `commands/get-clips-from-latest-video.ts` - includes `FileDoesNotExistError` 5. `commands/transcribe-clips.ts` - includes `transcribeClipSchema` 6. `commands/create-video-from-clips.ts` - imports `clipsSchema` from shared 7. `commands/send-clips-to-davinci-resolve.ts` - imports `clipsSchema` from shared, includes `NoInputVideosError` 8. `commands/move-raw-footage-to-long-term-storage.ts` 9. `commands/create-timeline.ts` 10. `commands/add-current-timeline-to-render-queue.ts` 11. `commands/export-subtitles.ts` 12. `commands/append-video-to-timeline.ts` 13. `commands/edit-interview.ts` 14. `commands/export-interview.ts` 15. `commands/move-interview-to-davinci-resolve.ts` 16. `commands/create-auto-edited-video.ts` - largest command, imports from `validate-cli-flags.ts` 17. `commands/log-latest-obs-video.ts` 18. `commands/queue-auto-edited-video-for-course.ts` 19. `commands/transcribe-video.ts` 20. `commands/process-queue.ts` 21. `commands/process-information-requests.ts` 22. `commands/article-from-transcript.ts` 23. `commands/queue-status.ts` - includes `formatRelativeDate`, `analyzeArticleWorkflows`, `generateProgressBar` 24. `commands/concatenate-videos.ts` 25. `commands/notify.ts` 26. `commands/retry-queue-item.ts` ### Phase 3: Final cleanup 27. Review `bin.ts` - should be ~50-80 lines: imports, program setup, command registrations, `program.parse()` 28. Delete any dead code, unused imports ## Decision Document - **Command file interface**: Each file exports `register(program: Command): void` that adds the command to the program - **Shared layer location**: `src/shared/main-layer.ts` exports `MainLayerLive` - **Shared schema location**: `src/shared/schemas.ts` exports schemas used by multiple commands - **Boilerplate handling**: Each command includes its own `.pipe(Effect.withConfigProvider(...), Effect.provide(MainLayerLive), NodeRuntime.runMain)` - no abstraction - **Error classes**: Stay with their command file (none are currently shared) - **Utility functions**: Stay with their command file (`formatRelativeDate`, `analyzeArticleWorkflows`, `generateProgressBar` stay in `queue-status.ts`) - **Naming**: Kebab-case matching command names ## Testing Decisions - **Build verification**: `pnpm run build` must pass after each commit - **Manual smoke testing**: User will manually test commands after refactor complete - **No new automated tests**: Pure structural refactor, behavior unchanged - **Existing tests**: `validate-cli-flags.test.ts` remains unchanged and must pass ## Out of Scope - Behavior changes to any command - Adding new tests for commands - Refactoring command internals - Changes to `@total-typescript/ffmpeg` package - Changes to existing extracted files (`tracing.ts`, `utils.ts`, `validate-cli-flags.ts`) - Creating abstractions for the repeated Effect boilerplate
