fix: allow strip_archive_path_components to strip a dir containing the same filename

[risu729]

mv .../age-plugin-yubikey/age-plugin-yubikey .../age-plugin-yubikey fails, so we need to rename the dir before moving the file.

Pull Request Overview

This PR fixes an issue in the archive path stripping functionality where it previously failed when a directory contained a file with the same name as the directory. The fix implements a temporary rename strategy to avoid filename conflicts during the file moving process.

• Replaces the previous two-phase approach (collect all files first, then move) with a safer single-phase approach
• Introduces temporary directory renaming to prevent conflicts when moving files out of directories
• Simplifies the logic by processing directories one at a time instead of collecting all entries first

Bug: Temporary Directory Collision Blocks Extraction

The temporary directory name generated by appending _tmp_strip could collide with an existing file or directory. This collision causes fs::rename to fail, stopping the archive extraction.

I think you can get around this with https://docs.rs/tempfile/latest/tempfile/struct.NamedTempFile.html#method.new_in

We need to rename the parent directory with a unique name, so I think we cannot directly use the tempfile crate.
We can use it to get a unique directory name, but it creates a tempdir and removes it immediately, so I think it's not good for performance.

Also, the directory name with _tmp_strip could collide, but I believe it's not a common case.
