<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Introduces a two-step deploy flow for edge functions: parallel
bundling followed by bulk activation, plus API shape updates.
> 
> - Adds `DeployedFunctionResponse` and updates `deploySupabaseFunction`
to support `bundleOnly`, return the deployed function payload, and use
`import_map_path`
> - Implements `bulkUpdateFunctions` (PUT `/projects/{id}/functions`) to
activate multiple functions at once
> - In `deployAllSupabaseFunctions`, filters to functions with
`index.ts`, bundles them in parallel (`bundleOnly=true`), aggregates
successes/errors, then bulk-activates successful bundles
> - Cleans up import map generation (`imports: {}`) and switches deploy
URL construction to include `bundleOnly` query param
