User custom tools support

Adds support for adding custom tools via Settings UI.
Write your own custom tool using JS, add a description in JSON, and Alice will be able to pick and use your new tool.
In-app validation, demo tool seeding.

Example workflow:

1. Open Settings → Customization
2. Upload or drop your script (writes to custom-tool-scripts/)
3. Click Add Tool, fill in metadata, and paste JSON schema. Saving updates to custom-tools.json
4. Toggle the tool on/off in the list. Only enabled + valid entries are offered to the model.
5. Use Refresh to re-read the file after manual edits.
6. The advanced editor lets you edit the JSON directly; the app validates the structure before persisting.
