Initial commit: linux-provision repo

Distribution-agnostic provisioning script that sets up a new Linux machine
(Detected via lib/distro.sh - supports Debian/Ubuntu/Pop and Fedora families).

13 stages covering:
- System packages, external repos, toolchains (nvm, uv, Python)
- Shell config (zsh, oh-my-zsh, p10k), git, SSH
- Custom uv tools from ~40 git repos
- Desktop config (keybindings, hotkeys, ghostty, fonts)
- Docker, system tweaks, browser/app installs
- Custom systemd user services (porridge, swayidle, mempi-sync, etc.)
- API keys loaded from Bitwarden at shell startup
