Add reversible reorganization previews

 ### Plugins and network
 
-- **PictView** decodes and encodes through [WIC](https://learn.microsoft.com/en-us/windows/win32/wic/-wic-about-windows-imaging-codec). The closed-source `pvw32cnv.dll` engine and `salpvenv.exe` envelope are gone. WIC covers mainstream formats plus OS codecs (HEIF, WebP, AVIF, camera RAW), but not the long tail of legacy formats the original engine handled.
+- **Reorganize** previews a folder reorganization in a `reorg:` panel and applies the reviewed moves through the host operation script. Plans are UTF-8 `.reorgplan` files. The plug-in does not copy files or delete them permanently.
 - **FTP/FTPS** uses Windows SChannel (no bundled TLS DLLs). Transfers are transactional and resumable, certificate exceptions are stored more safely, and passive FTPS data-channel TLS plus expired-exception compaction crashes were fixed.
 - FTP downloads keep an existing local file intact while receiving data into a unique sibling `.salftp-*.part` file. The matching `.meta` file records ownership and verified resume checkpoints. A move deletes its remote source only after local validation, flush, metadata, publication, and checked completion succeed. Cancellation or failure can leave these private files for a later retry; keep them together. Resume requires a matching remote version and unchanged local evidence. Legacy, corrupted, named-stream, reparse-point, or ambiguous publication states require manual inspection; a `.previous` sibling retains the old destination when publication cleanup cannot finish. Restart never replays remote deletion.
 - Bundled engines were upgraded: [7-Zip 26.02](src/plugins/7zip/doc/upgrade-26.02.md), zlib, SQLite (with defined recovery behavior), bzip2, and cmark-gfm.

+SDK 105 appends `ExecuteOperationSteps`, `EnumApplicationPathReferences`, and `GetApplicationDataDirectory` on `CSalamanderGeneralAbstract`. The Reorganize plug-in (`src/plugins/reorganize`) plans moves in a `reorg:` panel and asks the host to run the compiled steps through the existing durable operation script. The host does not copy or permanently delete for those steps. A step script keeps the plug-in loaded until `Finished` is delivered on the main thread.

 `CPluginInterfaceAbstract` (`src/plugins/shared/spl_base.h:469`) is the root contract. Capability flags and getters expose optional archive, viewer, menu-extension, filesystem, and thumbnail-loader interfaces. Common callbacks cover configuration, lifecycle events, history clearing, password-manager events, and path changes.
