Replace glob pattern with find command to properly clean dotfiles
in Trash when osascript fallback is used. The old pattern
~/.Trash/* does not match files starting with "." in bash.
This fix ensures that hidden files like .DS_Store, .hidden_file,
etc. are properly removed when cleaning the Trash.
Add unit tests for utility functions in cmd/status/view_test.go:
- formatRate: MB/s rate formatting with adaptive precision

Add unit tests for heap implementations in cmd/analyze/heap_test.go:
- entryHeap: min-heap for dirEntry (basic ops, empty, single element)
- largeFileHeap: min-heap for fileEntry (basic ops, top N pattern)
