fix(studio): add bun cache validation to Windows setup.ps1 (#4596)

Browse source 
Port the bun cache corruption fix from setup.sh to setup.ps1.

bun's package cache can become corrupt, storing only package metadata
without actual content. This causes bun install to exit 0 but leave
binaries like tsc missing from node_modules/.bin/.

Changes:
- After bun install, verify tsc and vite exist in node_modules\.bin\
- Check for both bare names and .cmd wrappers (Windows creates both)
- If missing, clear the bun cache and retry once
- Only fall back to npm if the retry also fails
