Two 18.x installs coexisted: VS2026 Community (full IDE, has VC v180)
and a BuildTools at (x86)\Microsoft Visual Studio\18\BuildTools that
has MSBuild but NO VC v180 targets. The vswhere query only required
Microsoft.Component.MSBuild, so -latest could (and did) return the
C++-less BuildTools -> MSB4019. Also require
Microsoft.VisualStudio.Component.VC.Tools.x86.x64 so only installs
with the C++ toolset match; the broken BuildTools is excluded and
2026\Community is selected. CI VM BuildTools has the C++ workload so
it still matches.

VS2026 ships on the prerelease channel; vswhere omits it unless
-prerelease is given. Without it _find_msbuild_via_vswhere returned
nothing, so the path fallback picked an incomplete
(x86)\Microsoft Visual Studio\18\BuildTools install (MSBuild present
but no VC v180 targets) -> MSB4019 on hosts that have VS2026 IDE but
not BuildTools. -prerelease is harmless on the CI VM (BuildTools is
found regardless).

Same --dist redirect (output to <repo>/dist/<config> instead of
plugins/<config>) applied to every per-version Windows script so the
flag works regardless of --7zip-version/--toolset the dispatcher
selects. Mirrors build_plugin_2601_vs2026.py + the Linux path.

When --dist is passed (forwarded by build_plugin.py to the per-version
script), built nsis7z.dll files are copied to <repo>/dist/<config>
instead of <repo>/plugins/<config>. Lets CI collect a clean dist/
tree without touching the committed plugins/ dir. Windows
(2601_vs2026) and Linux build paths both supported.

Aligns the zstd NSIS wrapper directory with the naming convention used by
all other bundle directories (versions/25.01-bundle, 26.00-bundle, etc.).
Changes:
- git mv versions/zstd -> versions/zstd-bundle (20 project-owned files)
- Fix UI/NSIS/StdAfx.h: use relative include ../../Bundles/Nsis7z/pluginapi.h
instead of absolute-style 7zip/Bundles/Nsis7z/pluginapi.h (portable across
both Linux and Windows builds without extra include path)
Build tool updates:
- tools/legacy/build_plugin_zstd_vs2026.py: updated project_dir path
- tools/linux/build_plugin_linux.py:
* VERSION_LAYOUT zstd: zstd -> zstd-bundle
* VERSION_EXTRA_FLAGS zstd: -Wno-sign-compare -Wno-cast-function-type
(fast-lzma2 C vendor code)
* VERSION_EXTRA_CXXFLAGS zstd: -Wno-unused-parameter (NSIS wrapper)
* EXTRA_SYS_OBJS: inject MyWindows.o for zstd (LocalFileTimeToFileTime2)
* Remove 'zip_version != zstd' exception; auto-recreate symlinks for all
bundle versions including zstd
- tools/linux/setup_bundle_symlinks.py: add VENDOR_DIR mapping so 'zstd'
points to versions/7-zip-zstd (not versions/zstd which no longer exists)
- tools/linux/overlay/makefile.gcc: add EXTRA_SYS_OBJS ?= variable so
callers can inject additional objects without modifying the file
Linux build status after this commit:
python3 build_plugin.py --7zip-version zstd -> Build completed (all 3 configs)
- tools/linux/build_plugin_linux.py: point VERSION_LAYOUT['25.01'].bundle_dir
to versions/25.01-bundle/; update comment (all versions now use bundle dirs).
- tools/legacy/build_plugin_2501_vs2026.py: point project_dir to 25.01-bundle/.
- tools/legacy/build_plugin_2501_vs2022.py: point project_dir to 25.01-bundle/.
- tools/linux/build_plugin_linux.py: point VERSION_LAYOUT['26.00'].bundle_dir
to versions/26.00-bundle/ (was versions/26.00/); update module docstring.
- tools/legacy/build_plugin_2600_vs2026.py: point project_dir to
versions/26.00-bundle/ (was versions/26.00/).
- tools/linux/setup_26_01_bundle_symlinks.py: refactor to use bundle_root /
vendor_root variables and add C/Asm root-level symlink creation, matching
the new setup_26_00_bundle_symlinks.py convention.
- Add tools/legacy/build_plugin_2601_vs2026.py: Windows build script for
7-zip 26.01 using VS2026 toolset (v145), adapted from the zstd equivalent.
Points to versions/26.01-bundle/ as the project root.
- Update build_plugin.py:
- Add LINUX_SCRIPT reference to tools/linux/build_plugin_linux.py.
- Add '26.01' to WINDOWS_SCRIPTS with v2026 entry pointing to the new
script (v2022 remains None; 26.01 requires v145 minimum).
- Add '26.01' to LINUX_SUPPORTED_7ZIP set.
- Add '26.01' to argparse choices.
- Implemented plugin API in `pluginapi.cpp` and `pluginapi.h` for NSIS integration.
- Added resource files `resource.h` and `resource.rc` for versioning and resource management.
- Created `ExtractCallbackConsole` class to handle extraction progress and user input.
- Developed main extraction logic in `Main.cpp` and `MainAr.cpp` for handling archives.
- Introduced user input utilities in `UserInputUtils2.cpp` and `UserInputUtils2.h` for password handling and user prompts.
- Added break signal handling in `NSISBreak.cpp` and `NSISBreak.h` for graceful interruption of extraction processes.
- Included standard header `StdAfx.h` for precompiled headers and common includes.
