Subject: [PATCH] fix: refresh Files tab after decompressing ZIP from preview
 screen

When a ZIP is opened from the Files tab, its contents are shown in
DecompressActivity, which is launched via an implicit ACTION_VIEW intent
rather than startActivityForResult. On successful extraction the activity
only toasted and finished, so MainActivity had no way to learn that new
content was written and its onResume never re-read the current directory.
The extracted folder therefore only appeared after a manual swipe-to-refresh.

DecompressActivity now records the extracted folder path in a plain-String
companion field (no Activity reference, so no leak) and MainActivity consumes
it on resume, navigating the Files tab into the freshly extracted folder.
Both the write and read happen on the main thread, so no synchronization is
needed.

Closes #194
