fix windows file lock issue

[phrogwrld]

When running the command bun db:push or bun db:push:local:

PS C:\Users\phrog\Code\_\web> bun db:push:local
$ bun ./prisma/push.mjs --local
No changes
83 |    unlinkSync(tempDb);
84 |    process.exit(0);
85 | }
86 | if (migration.stdout.includes('-- This is an empty migration.')) {
87 |    console.log('No changes');
88 |    unlinkSync(tempDb);
      ^
EBUSY: resource busy or locked, unlink 'C:\Users\phrog\Code\alignofficesystems\web\prisma\temp.db'
    path: "C:\\Users\\phrog\\Code\\alignofficesystems\\web\\prisma\\temp.db",
 syscall: "unlink",
   errno: -16,
    code: "EBUSY"

      at C:\Users\phrog\Code\alignofficesystems\web\prisma\push.mjs:88:2
      at loadAndEvaluateModule (2:1)

Bun v1.2.20 (Windows x64)
error: script "db:push:local" exited with code 1

At first, I thought it was corrupted windows OS, but testing with a fresh install also gave me the same issue.

This happens because Windows will lock in-use files, which prevents unlinkSync from removing temp.db.

This appears to be Windows-specific because I didn't experience this issue on Linux.
