Problem & expected behavior (under 200 words)

tsx version: 4.21.0
OS: Windows 11

Describe the bug
tsx watch --exclude cannot exclude files in parent/adjacent directories.

I'm running tsx watch in:
F:\pro\testtaro\apps\honoapp

But it keeps watching and restarting on changes from:
F:\pro\testtaro\apps\reactapp\node_modules\.vite-temp\*.mjs

To Reproduce
Run:
tsx watch --exclude "/*.mjs" --exclude "../reactapp//*.mjs" src/index.ts

Expected behavior
--exclude should ignore files in parent/adjacent directories.

Actual behavior
Files in parent/adjacent directories still trigger restart.
