## Summary
* Adds a `delete_notebook` AI assistant tool (`needsApproval: true`)
that lets the assistant delete a notebook with explicit user approval,
mirroring the existing `create_notebook`/`update_notebook` tools.
* Wires up a destructive-styled approval card in the AI Assistant Panel
(fetches the notebook to show its name, warns the deletion is permanent)
using the same `Confirm`/tool-approval plumbing as the other notebook
tools.
* Updates `tool-filter.ts` opt-in gating, the assistant system prompt,
the eval-harness mock tools, and the eval dataset with `delete_notebook`
coverage.
* Adds test coverage in `notebook-tools.test.ts`, `mock-tools.test.ts`,
and `NotebookProposalRenderer.test.tsx`.
Closes
[FE-4242](https://linear.app/supabase/issue/FE-4242/assistant-delete-notebook-tool).
## Test plan
- [X] `pnpm typecheck --filter=studio` passes
- [X] `pnpm --filter studio exec vitest run` for the touched files
(notebook-tools, mock-tools, NotebookProposalRenderer,
[Message.Parts](<http://Message.Parts>), and existing consumers of
`content-delete-mutation`) — all passing
- [X] `eslint` and `prettier --check` clean on all touched files
- [X] Manual verification of the approval UI in a running Studio
instance (not done in this session)
