fix: restore full pattern + fix Next.js 16 Turbopack warnings

[lars-hagen]

This PR restores the original full pattern **/*.{jsx,tsx,js,ts,mjs,mts} for code-inspector and fixes Next.js 16 Turbopack configuration warnings.

Background

The original pattern was restricted in two previous PRs due to a Turbopack middleware crash bug:

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

The Turbopack crash bug was fixed in Next.js 15.6.0-canary.22, but 15.6.0 was never released as stable. Next.js jumped from 15.5.6 directly to 16.0.0 (Oct 22, 2025).

What This PR Does

1. Restores full pattern: Returns to **/*.{jsx,tsx,js,ts,mjs,mts} to properly cover all project files
2. Fixes Next.js 16 warnings: Removes unrecognized enforce keys that cause config warnings in Next.js 16
3. Updates demo: Upgraded to Next.js 16.0.1
4. Renames demo folder: turbopack-next15 → turbopack-next to avoid version number maintenance

Testing

Tested with Next.js 16.0.1 - no warnings, full file coverage restored.

Updated this PR for Next.js 16!

Next.js 15.6.0 was never released as stable - Vercel jumped from 15.5.6 directly to 16.0.0 (Oct 22, 2025).

Changes:

• Demo updated to Next.js 16.0.1
• Fixes the enforce key warnings in Turbopack config
• Demo folder renamed to turbopack-next (no more version number maintenance)

This is now ready to merge with full Next.js 16 support!
