`getCurrentValue()` to `"deep"` when Pro Smart Files mode is enabled
without an explicit option.
> - Engine (`src/ipc/handlers/chat_stream_handlers.ts`):
`isDeepContextEnabled` now requires `enableProSmartFilesContextMode` and
treats any option other than `"balanced"` as deep; `smartContextMode`
set accordingly and `versioned_files` used when deep.
> - **Snapshots**
> - Update e2e snapshots to reflect `smart_context_mode: "deep"` and new
`dyad_options.versioned_files` structure.

## Summary by cubic
Default smart files context to deep and align the UI and stream handler
so anything not “balanced” uses deep when Pro Smart Files mode is on.
This prevents mismatches and makes deep context the default.

- **Bug Fixes**
  - ProModeSelector: default to deep when no option is set.
- chat_stream_handlers: isDeepContextEnabled requires Pro Smart Files
mode and treats non-“balanced” as deep; smartContextMode set to deep
accordingly.
  - Engine payload: use versioned_files; update e2e snapshots.
