OpenClean: all versions and old releases

Added
- Deep system cleanup as its own tab, covering five areas Windows keeps to itself: the previous installation (Windows.old), the component store (WinSxS), shadow copies, the Windows Update cache and the Delivery Optimization cache. Every area is measured before anything is touched and confirms separately before it deletes.
- Occupied space and reclaimable space are shown as two different numbers, because they rarely match, and freed space is measured before and after instead of estimated.
- Network transparency (local) as its own tab: a live view of which programs hold connections to the outside, with process name and path, remote address and port, and connection state. The view only reads - it never blocks, throttles or alters a connection, and reverse DNS lookup is off by default.
- Drive health in "Storage & RAM": every physical disk gets a verdict - healthy, keep an eye on it, or failure likely - read locally from SMART through Windows, with no vendor tool and no online lookup. The verdict stays free; the individual readings (temperature, life remaining, power-on hours, power cycles, reallocated and pending sectors, total bytes written) are part of OpenClean Pro.
- Real NVMe SMART values for NVMe SSDs - power-on hours, power cycles and total bytes written - decoded from the NVMe health log page, plus power cycles for USB drives. Whatever no source reports stays empty instead of being shown as zero.
- A central settings area behind the gear icon in the title bar, bundling theme, language and licence management in one place.
- A theme picker with Cyberpunk, Gaming-RGB, Nord, Catppuccin, Dracula, Dev and Windows 11 styles, switchable live without a restart, plus an optional Windows accent colour, a real Mica/Acrylic backdrop on Windows 11 and a "reduce animations" switch.
- The cookie inventory on the privacy page lists cookie names per domain with a live search, and now reads cookie databases while the browser is open - without creating a volume shadow copy, which would discard your older restore points.

Changed
- Cleanup and Deep Clean are grouped under a single expandable "Cleanup" entry in the sidebar.
- The entry in "Add or remove programs" is now named "OpenClean" without the version number.
- Internal restructuring toward MVVM and clean-code principles, with no change to behaviour or performance: dialog and UI-thread access now go through interfaces, and the largest classes were split into focused parts.

Performance
- The main lists - installed programs, network connections, startup entries, updates and context-menu entries - are UI-virtualised, and the installed-programs list no longer re-sorts once per item while it fills.
- The Restore area reads backup sessions and restore points in the background, the RAM waveform caches its drawing resources instead of rebuilding them every frame, and duplicate image previews are decoded once and cached.

Removed
- The separate "Pro" entry at the bottom of the sidebar; licence status and activation now live in the central settings area.

Fixed
- The cookie scan silently returned nothing when the database was locked.
- The "Cookies" category stayed empty during a privacy scan while the inventory above it was full.
- The privacy page could not be scrolled, leaving "Browser history" and everything below it out of reach.
- The cookie search box was rendered unstyled.

Added
- Safety net for deletions: create Windows restore points before cleanup and back up files before deletion, so entire runs can be undone. Both features are individually toggleable.
- Restore view: undo backed-up runs from Cleanup, Duplicates, Leftovers, Privacy and Large files sections, or discard backups.
- Windows restore point management: view, delete individual points, remove all but the most recent, and open system rollback via rstrui.exe.
- Storage & RAM analysis: sunburst visualization; click segments to zoom into folders and find space-consuming items.
- Large files finder tab: locate and move large files to the Recycle Bin, with warnings when files exceed bin capacity.
- Context menu management: disable Windows right-click menu entries without deleting anything.
- Delayed startup: stagger startup programs after sign-in instead of launching them all at once.
- License page: activation status, device release info and Pro feature overview.

Changed
- Recycle Bin moves now batch up to 128 paths per shell call, greatly improving performance for cleanups with many temporary files.
- Scheduled cleaning and batch uninstall moved to the Premium module; the core stays free and open source.

Fixed
- Restore point timestamps corrected (previously shifted by UTC offset).
- Large files deleted from the finder now correctly appear in the Restore view.

Security
- Self-check on startup: verifies the executable signature and locks modifying functions if the file was altered.
- Restricted DLL search path limited to System32 to prevent loading unauthorized libraries.

First public release: overview dashboard, storage & RAM, cleanup with preview, startup manager, privacy scanner, uninstaller with leftover scan, and a SHA-256 duplicate finder. 7 languages.
