Changes in this commit

Removed all _codeql_build_dir/ contents and _codeql_detected_source_root symlink that were unintentionally committed. Added these patterns to .gitignore to prevent future accidental commits of CodeQL build artifacts.

Original prompt

I would like you to implement a new component in viamd called particlesystem which simulates particles in vector fields. The input format for the particle system are volumes with 4 components, encoding a gradient in xyz and the scalar value in w. The particle system should use compute shader(s?) to seed, advect and handle lifetimes of particles. The seeding strategy for the first iteration can be based on randomly placing points within the regions where the scalar value is within a certain range.
For rendering, since the vector field is static, I'm thinking of having particles with trails that fade out its opacity to provide a hint of where they came from.

I want you to prune and remove everything which has to do with codeql that you introduced into this PR. I have no idea why you bloated this PR with that?

Removed all CodeQL build artifacts from the PR in commit 6ae828b. The _codeql_build_dir/ directory and symlink have been deleted and added to .gitignore to prevent future accidental commits. The build still works correctly.
