add app-text/tree

"Lists directories recursively, and produces an indented listing of files."

Clean build and tested OK.

It is very helpful if you include the project/app's url in the ticket itself, instead of the just the bep file.

Other than that, it looks like a useful app.

Applied in r2026. Note the addition of DESTDIR and finddir to hep make the distro package correctly and to locate correct directories if/when Haiku moves their locations in a future change.
