Bun install files permission

What does this PR do?

Try fix #14467

• Documentation or TypeScript types (it's okay to leave the rest blank in this case)
• Code changes

How did you verify your code works?

I just test it on my local machine. I'll write a test for it.

• I checked the lifetime of memory allocated to verify it's (1) freed and (2) only freed when it should be
• I included a test for the new code, or an existing test covers it
• JSValue used outside outside of the stack is either wrapped in a JSC.Strong or is JSValueProtect'ed
• I wrote TypeScript/JavaScript tests and they pass locally (bun-debug test test-file-name.test)

Thank you for highlighting that this is an issue - but this approach is going to cause a meaningful performance regression by adding an extra loop over all the files. We can make this work without regressing on performance by setting the mode during extraction without adding an extra pass over the input. I'll defer to @dylan-conway on this for what the behavior should be to align with npm/pnpm/yarn

Oh, that will be great! I'm new to zig and bun, just try to fix my issue. Know that chmod at unpack stage will be the best practice, but I don't know how to do it, so just try to implement with another approach.

Wish we can ASAP to fix this, cause I can't use bun to install packages, thx ❤️.
