When a file or directory has a separate 8.3 short name, it appears in the NTFS
directory index twice: once under its Win32 long name and once under the Dos
short name. The extractor iterated all index entries, so every such item was
written a second time under its mangled NAME~1.EXT alias — and short-named
directories had their entire subtree re-extracted.
Skip index entries in the Dos namespace (the file is still extracted via its
Win32 entry). Add unit tests for the skip decision.

Output directory is now derived from the input .app path (without
extension) instead of the intermediate VHD filename.

Replace Set-VHD + Merge-VHD PowerShell cmdlets with a pure Rust
MergedVhdReader that overlays delta blocks on the base VHD using
the sector bitmap to decide which sectors come from which disk.
No actual merge to disk needed — reads directly from both files.
- No admin privileges or UAC prompts required
- No Hyper-V or PowerShell dependency
- Cross-platform (works on Windows and Unix)
- Remove #[cfg(windows)] from merge/extract path

- Move VHD parsing and NTFS extraction to src/vhd.rs
- Replace all hardcoded magic values with named constants
- Extract shared progress bar style to constant
- Simplify main.rs merge/resolve logic with helper functions
- Condense formatting without changing behavior

Replace PowerShell-based VHD mounting (Set-VHD/Mount-VHD/Copy-Item)
with a pure Rust implementation. New src/vhd.rs module:
- VhdReader<R> parses fixed and dynamic VHD formats
- Handles MBR partition tables and NTFS offset detection
- Dynamic VHD support with BAT (Block Allocation Table) parsing
- Recursive NTFS directory extraction with timestamp preservation
- No elevation, no Hyper-V, works cross-platform
