Discuss: Git LFS strategy for large binary files

[tobias-weiss-ai-xr]

Context

The .gitattributes cleanup (PR #41) revealed several large binary files in the repo that could benefit from Git LFS:

Path	Description
Common/3dParty/libvlc/build/**	VLC precompiled binaries (~302 MB, 5 platforms)
Common/DesktopEditor/xmlsec/src/wasm/**	Emscripten WASM binaries
Test/Applications/**/bin/**	Compiled test binaries
Test/Applications/**/obj/**	Compiled test objects

Open questions

• Can libvlc binaries be removed entirely once vgpkg is in place? (@juliusknorr)
• Are the WASM binaries still needed? (@rikled)
• Can compiled test artifacts be dropped or generated via CI? (@DmySyz)
• If any remain, should we use Git LFS, build from source, or package separately?

Proposal

Decide which binaries to remove vs. keep, then implement the chosen strategy in a follow-up PR.
