Add BSA in-memory extraction and nested preview support

bsatk:
- Archive::extractToMemory() extracts a file directly into a byte buffer
  instead of a filesystem path, backed by a std::ostringstream sink.
- Archive::findFile() locates a file by relative path, case-insensitive
  and separator-agnostic, walking the folder tree recursively.
- extractDirect/extractCompressed now take std::ostream& so both the
  ofstream and ostringstream paths share the same implementation.

libbsarch: shim rewrite on Linux to map the Windows API surface onto
bsatk::Archive, enabling preview_bsa to open vanilla BSAs via the
same interface as other plugins.

preview_bsa: double-click on a file in the BSA tree now extracts the
bytes via extractToMemory() and hands them to IOrganizer::previewFileData
for nested preview rendering (e.g. NIF inside a BSA).

uibase + organizerproxy + organizercore: new IOrganizer::previewFileData
virtual that routes in-memory file bytes through the first registered
IPluginPreview matching the extension. Uses heap + WA_DeleteOnClose +
open() to avoid nested exec() softlock from mod info filetree ->
preview_bsa tree -> nif preview.

docker/build-inner.sh: stage preview_nif shaders into plugin_data/shaders
so ShaderManager can load them via IOrganizer::getPluginDataPath().

+// Linux implementation backed by bsatk.
+//
+// libbsarch is a Delphi-based archive library on Windows. Upstream MO2 uses
+// a prebuilt DLL from vcpkg. On Linux we have no such runtime, so previously
+// this file was a set of no-op stubs — which meant anything that went through
+// the C++ wrappers (bs_archive::load_from_disk / extract_to_memory, used e.g.
+// by the data-tab preview pipeline in OrganizerCore) silently returned empty.
+//
+// This replacement wires the read path through BSA::Archive from libs/bsatk,
+// which is a pure C++ BSA reader already built and linked in MO2. The write
+// side (creating archives, adding files, saving) is still stubbed; bsapacker
+// linked against that stub before and keeps linking against it now.
