chore: update linker flags, clean build artifacts, and refactor import paths

- Add -lstdc++exp to VSCode C++ linker flags for experimental C++ features
- Remove generated cpptrace build artifacts (cmake configs and version header)
- Update atom submodule to dirty state
- Refactor example includes to use new modular paths:
  * components/manager.hpp → components/manager/manager.hpp
  * task/sequencer.hpp → task/core/sequencer.hpp
  * task/target.hpp → task/core/target.hpp
- Apply black formatting to isolate
