Improvements to auto-activate (experimental)

▎ Auto-activate is behind a feature flag. Enable it with flox config --set features.auto_activate true (or FLOX_FEATURES_AUTO_ACTIVATE=true).

• Declining the auto-activation prompt for an environment is now remembered, so you are no longer prompted for it again.
• Re-allowing a previously denied environment in the middle of a nested auto-activation stack now restores it to its correct position in the prompt and PATH, matching what a fresh cd into the directory produces.
• The auto-activation prompt no longer hangs when using the fish shell.

Features

• flox run now supports running packages from custom catalogs (e.g. flox run owner/pkg), using an authenticated download path.

Fixes

• flox gc and flox envs no longer fail with Failed to fetch environment: ref not found when a deleted environment is still referenced by the local environment registry.
• flox install no longer prints the "additional outputs" hint when you explicitly selected outputs (pkg^.. or pkg^out,man).
• The "Your FloxHub token has expired" reminder is now shown once per shell session instead of repeating for nested flox invocations.
• flox install pkg^bad with an invalid output name now shows a clear error instead of a raw Nix build trace.
• flox activate no longer crashes on a rare race in activation cleanup.
• Installing flox via the Nix module no longer emits a 'system' has been renamed evaluation warning.
