create with bun says Intent is configured but never writes AGENTS.md

tanstack create with bun prints TanStack Intent configured and claims AGENTS.md was wired up, but the command it ran failed. No agent config is written. Deps install fine — it's just the Intent step.

Errors were encountered during the creation of your app:

Command "bunx --bun @tanstack/intent install" did not run successfully. Please run this manually in your project.

After that, node_modules is there, AGENTS.md isn't, and node_modules/.bin/intent points at @tanstack/devtools/bin/intent.js.

Same command inside the app:

bunx --bun @tanstack/intent install

exits immediately with @tanstack/intent is not installed. — no registry fetch.

Two things going on:

1. bunx is running the intent shim from @tanstack/devtools, not the real package. bunx --bun @tanstack/intent@latest install does download, then hits:

   Permissions: failed: intent.skills is not configured.
   

2. Intent 0.4.0 wants a TTY to write package.json#intent.skills on first run (TanStack/intent#241). create still treats intent install as non-interactive (#442).

Not the same as #495 — that one is --no-install. This happens with deps already installed.

#513 uses @tanstack/intent@latest (same as shadcn@latest) and writes intent.skills: ["@tanstack/*"] before install.

@tanstack/cli 0.71.0, bun 1.3.1, macOS

Run the exact tanstack create command with Bun and --intent, then reproduce bunx --bun @tanstack/intent install inside the generated app. Trace the create command's Intent installation path and compare it with #513; done means the intended package is installed, intent.skills is configured as needed, and AGENTS.md is written without reporting a false success.
