Would cut a new release soon once this PR is merged.

No worries, github ux isn't exactly the most clear with that ;)

Looks good, can you try setting the env locally and see if it prints the debug output as expected please?

Okay so I tried it in 2 spots, I think it's good

1 is building tree-sitter with cargo build/install, that seems to show the appopriate output when the env var is set with -vv tacked on.

2 is when tree-sitter builds and runs cc at runtime to compile parsers, setting the env var correctly displays the output that was previously force printed always.

So I think it's good now, this is much better than before

Thank you!
