fix: restore full pattern after Next.js 15.6 Turbopack fix

[lars-hagen]

Summary

This PR proposes reverting the Turbopack pattern restrictions introduced in #398 and #399 once Next.js 15.6.0 is released as stable.

The underlying middleware crash bug has been fixed in Next.js 15.6.0-canary.22, allowing us to restore full code-inspector coverage across the entire codebase by returning to the original **/*.{jsx,tsx,js,ts,mjs,mts} pattern.

Context

Previous workarounds (no longer needed):

• PR fix(turbopack): restrict default pattern to app directory to prevent middleware crashes #398: Restricted to **/app/**/*.{jsx,tsx,js,ts,mjs,mts}
  • Problem: Missed components/, lib/, hooks/, etc.
• PR fix: improve the file scope of nextjs #399: Changed to **/*.{jsx,tsx} + specific Next.js routing files (layout.js, page.ts, etc.)
  • Excluded all regular .js, .ts, .mjs, .mts files to avoid middleware

These restrictions were necessary to avoid the Turbopack middleware crash documented in:

• Edge Runtime error with webpack loaders when middleware exists: "path.join is very dynamic" vercel/next.js#83613
• nextjs15.4 turbopack runtime error #357

The fix:
The underlying Turbopack bug has been fixed in Next.js 15.6.0-canary.22 via vercel/next.js#83683

Changes

1. Reverts to original full pattern: **/*.{jsx,tsx,js,ts,mjs,mts}

   • Restores coverage for all file types across the entire codebase
   • No longer restricted by directory or file extension
   • Works everywhere: components/, lib/, hooks/, app/, etc.

2. Removes enforce property: Not supported in Next.js 15.6+

3. Updates demo to Next.js 15.6.0-canary.38: Proves the fix works

Status

⚠️ This is a placeholder PR for consideration ⚠️

• Currently uses canary version 15.6.0-canary.38
• Should be merged once 15.6.0 is released as stable
• Demonstrates that the original full pattern now works without crashes

Testing

• ✅ Middleware file present (previously caused crash)
• ✅ Code inspector works across entire codebase
• ✅ No Turbopack errors with full pattern
• ✅ Demo runs successfully with pnpm dev

Thank you for your PR, I believe this PR can be merged after the official release of NextJS 15.6.0.
