## Summary by cubic
Prototype custom theme generator that lets users create themes manually
or generate prompts from images, manage them from a new Themes page, and
apply them in chat. Themes are global and used in streaming and token
counting.

- **New Features**
  - Added custom_themes table.
- Implemented IPC and hooks to list/create/update/delete themes with
query cache invalidation.
- New CustomThemeDialog with manual prompt entry and prompt generation
from uploaded images and optional keywords; uses the selected model via
Dyad Pro and requires Dyad Pro enabled.
  - New Themes page with CRUD, EditThemeDialog, and a sidebar link.
- Updated chat Themes menu to show built-in plus recent custom themes,
with “New Theme” and a “More themes” dialog; newly created themes
auto-select and selection persists per app.

- **Refactors**
- Replaced getThemePrompt with async getThemePromptById to support
custom theme IDs (custom:<id>); integrated in chat_stream and
token_count handlers.
  - Whitelisted new IPC channels in preload.

<sup>Written for commit 37d9e5f0c477e2bb0847df506450b45a25ab4874.
Summary will update on new commits.</sup>
