Charis 4da8bfe469 feat(studio): wire update_notebook tool (#48949)
## Summary
- Adds `update_notebook`, an AI tool (`needsApproval: true`) that
re-fetches a notebook, applies an ordered list of cell operations
(insert/replace/delete/move, from `notebook-operations.ts`) via
`applyNotebookOperations`, and PUTs the resolved content. Concurrent
edits are last-write-wins, since re-fetching at execute time is the only
mitigation per the RFC.
- Registers `update_notebook` in `toolSetValidationSchema` /
`TOOL_CATEGORY_MAP`, and documents it in the notebooks system prompt.
- The untrusted→safe SQL promotion
(`acceptUntrustedSql`/`acceptUntrustedLogsSql`) is inlined directly
inside each `needsApproval: true` tool's own `execute` (both
`create_notebook` and `update_notebook`), rather than behind a shared
helper — kept auditable right next to the approval gate that authorizes
it, and not reusable by an unrelated caller unaware it needs
re-promotion.

Resolves FE-4083

## Test plan
- [x] `notebook-tools.test.ts`: re-fetch → apply operations → PUT with
promoted SQL; descriptive error (no PUT) when an operation targets an
unknown cell id; `needsApproval` asserted for both create and update
- [x] `pnpm vitest run` on `notebook-tools.test.ts`,
`tools/index.test.ts`, `tool-filter.test.ts` — all pass
- [x] `tsc --noEmit`, `eslint`, `prettier --check` — clean on all
touched files

## Summary by CodeRabbit

* **New Features**
* AI-assisted notebook editing now supports updating existing notebooks.
* Notebook changes are refreshed before being applied to help preserve
the latest content.
* Updates report operation errors and return a summary of the modified
notebook.
  * Notebook edits require user approval before being saved.

* **Bug Fixes**
* Invalid or unknown cell references are reported without applying a
partial update.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
