towel export doesn't work from within towel

[MFelida]

towel export only works when ran from the host.

I tried to reproduce this on current main (v0.2.1) and towel export works for me both from the host and from within the container, so I'd like a bit more detail to pin down the failure.

My setup: quay.io/fedora/fedora-toolbox:rawhide container, dnf5 5.4.2.1.

• From host: towel export bash → wrappers created in ~/.local/share/towel/exports/bin/ + symlinks in ~/.local/bin. ✅
• From within (distrobox enter towel, then towel export bash): same result. ✅

Inside the container I see CONTAINER_ID=towel in every shell, so inside_towel() returns true and the dispatch falls through to towel_auto_export. dnf repoquery -l bash returns the file list on stdout (repo-load progress goes to stderr), and the wrappers get written to the host ~/.local/bin fine.

Could you share, for the within-towel case:

1. The exact command and package you ran (towel export <pkg>).
2. The full output / any error.
3. Whether the package was installed in the container first (towel export only wraps files that exist on disk via the [ -e "$file" ] guard).
4. Environment specifics — e.g. running on intra (proxy/network for dnf metadata) vs a local machine, and the image from your towel.ini.

That'll help confirm whether it's a code path or environment-specific (e.g. dnf metadata refresh) issue. Happy to PR a fix once I can reproduce it.
