New features:
- Linux Flasher tab: download+decompress+flash pipeline for RPi OS, Ubuntu,
Debian, Fedora, Kali, DietPi, Alpine, Arch ARM with built-in image catalog
- Kali Creator tab: 4 sub-tabs for USB/SD, VM creation, Docker/Podman
container pulls, and cloud image downloads
- DownloadManager: async downloads with resume support and speed tracking
- Decompressor: streaming .xz (xz-embedded), .gz (zlib), .zip decompression
- ImageCatalog: built-in catalog + remote fetch from rpi-imager JSON endpoint
- SevenZipExtractor: QProcess wrapper for 7z.exe with progress parsing
- Bundled xz-embedded third-party library for native XZ decompression
Bug fixes:
- Fixed VirtualDisk::flashToDisk() — added FSCTL_ALLOW_EXTENDED_DASD_IO,
FSCTL_LOCK_VOLUME, FSCTL_DISMOUNT_VOLUME, 32MB aligned buffers,
WriteFile retry logic (3 attempts), FlushFileBuffers before close
- Fixed VirtualDisk::captureFromDisk() with same improvements
- Fixed ImagingTab::onFlashIso() — now populates targetVolumeLetters from
disk snapshot so IsoFlasher can properly lock/dismount volumes
- Fixed SD card counterfeit detection false positives:
- Changed from write-one-read-one to write-all-then-read-all algorithm
to properly detect NAND address wrapping on fake cards
- Added volume lock/dismount before probing to prevent filesystem
interference (journal writes, metadata updates)
- Added FSCTL_ALLOW_EXTENDED_DASD_IO for probes near end of disk
- Fixed overly aggressive vendor string check — USB card readers
legitimately report "USB"/"Mass Storage", no longer flagged
- Added handle re-open between write and verify phases to defeat
USB reader hardware cache
- README: documented how to unlock the secret menu, added new feature docs
