Commit Message

feat(studio): switch dashboard assistant to remote MCP server (#47479)

## I have read the
[CONTRIBUTING.md](<https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md>)
file.

YES

## What kind of change does this PR introduce?

Feature / refactor.

## What is the current behavior?

The dashboard assistant runs `@supabase/mcp-server-supabase` in-process
over an in-memory transport (`lib/ai/supabase-mcp.ts`).

## What is the new behavior?

The assistant connects to the **remote MCP server** over HTTP
(`@ai-sdk/mcp`), forwarding the dashboard session token as a bearer. URL
comes from `NEXT_PUBLIC_MCP_URL` with a local-dev fallback;
platform-only, and Nimbus works via the same env var.

* **Tool model unchanged:** UI-controlled `execute_sql` (with
`needsApproval`) and `deploy_edge_function` still come from Studio; the
allowlist (`TOOL_CATEGORY_MAP`) remains the gate keeping the remote's
write tools away from the assistant (`read_only` is defense-in-depth).
* **Attribution:** sends `x-source-name: supabase-studio` (+
`x-source-version`) → logged as `source_name`/`client_name`.
* **Connection lifecycle:** the HTTP client is closed via the request's
`AbortSignal` (tools execute later during streaming); `signal` is
required on `getTools`/`getMcpTools`.
* **Resilience:** a remote-MCP failure degrades to the remaining tools
instead of failing the assistant.
* **Drift protection:** relied-upon tools are typed against `keyof
typeof supabaseMcpToolSchemas`, so a package bump that renames/removes
one fails `pnpm typecheck`; a runtime check also warns if the deployed
server returns fewer tools.
* Adds unit tests for the above.

## Additional context

* Verified end-to-end against a local remote MCP server with a dashboard
token: `initialize` 200, tools listed, a tool executed, client closed
cleanly.
* The remote MCP (mgmt-api) already accepts dashboard session tokens
(GoTrue-JWT auth path) — no backend change needed. `NEXT_PUBLIC_MCP_URL`
must point at each... (continued)
