00_env.sh:
- yaml2json: use python3 (python3 first, python fallback) — Ubuntu 20+ has no 'python'
- pyenv init: moved out of Darwin-only block; now runs everywhere if pyenv installed
- xterm ls alias: split by OS — Linux gets 'ls --color=auto', macOS gets 'ls -G'
10_aliases.sh:
- psg: guard with 'command -v pstree' (not installed by default on Ubuntu)
- ps-m: Linux-only (--sort flag is GNU ps, not available on macOS)
- gitresetpw: OS-conditional — osxkeychain on Darwin, store on Linux
dotfiles_manager.sh:
- Replace both hardcoded 'brew install gnupg' die messages with _require_gpg()
helper that gives apt-get hint on Linux and brew hint on macOS
