fix: Preallow esbuild build when installing Storybook

[Sidnioulz]

Closes #499.

This mirrors the change we're making to Storybook itself, to preapprove the build of esbuild for PNPM users. Storybook has a hard dependency on esbuild at the moment and so users have to approve that build to use Storybook.

Alternatively, I'm happy to change the TanStack CLI to include a manual approval step (with a clean exit on user refusal to build esbuild, and whatever changes you deem relevant for non-interactive invocations of the CLI).

Summary by CodeRabbit

• New Features
  • Storybook setup now allows the esbuild build script to run when using pnpm.
  • Add-on and starter commands can specify build scripts that pnpm is allowed to run.

📝 Walkthrough

Command definitions now pass optional allowBuilds values through command translation. For pnpm, each value adds a --allow-build flag before dlx. Create commands pass add-on and starter values, and the Storybook add-on allows esbuild.

Changes: pnpm build approval

Layer / File(s)	Summary
Define and translate build approval options packages/create/src/types.ts, packages/create/src/package-manager.ts, packages/create/tests/package-manager.test.ts	The add-on command schema and execute-command translation support optional allowBuilds. pnpm adds one --allow-build=<package> flag per value before dlx; other package managers keep their existing command construction. Tests cover populated and empty lists, plus translation behavior.
Wire build approvals into create commands packages/create/src/create-app.ts, packages/create/src/edge-create-app.ts, packages/create/src/frameworks/react/add-ons/storybook/info.json, .changeset/storybook-pnpm-allow-build.md	Add-on and starter command translation receives each command’s allowBuilds value. The Storybook add-on allows builds for esbuild. A patch changeset describes the update.
