Integrate Darwin branch features into integration branch

- Add AeroSpace window manager configuration and file setup
- Add LazyVim setup with gh-addressed plugin
- Add Darwin-specific secrets (work key + work-wg.age)
- Reorganize kitty config into separate profile
- Make Linux-only packages conditional (iputils, strace, vim-tidal)
- Fix nix-darwin compatibility (remove deprecated options, add primaryUser)
- Update font packages to new nerd-fonts structure
- Add platform-aware nrb alias (detects Darwin vs Linux)
- Use shared tmux config instead of Darwin-specific duplicate
- Update Darwin host config (disable yabai, enable AeroSpace)
- Fix sketchybar permissions and gitignore .direnv tracking

Integration branch now works on both Darwin and Linux with all Darwin improvements.
