Migrate to chezmoi with per-host sway/waybar configs

- Restructure repo into chezmoi source layout (dot_ prefix)
- Add .chezmoi.toml.tmpl mapping hostname to hosttype (laptop/desktop)
- Template sway config.d fragments (outputs/inputs/binds) per host
- Template waybar config.jsonc with shared bar/module definitions
- Host-scope pulsemeeter (flow) and teams-for-linux (desktop hosts) via .chezmoiignore
- Trim install.sh package lists to configured software + config deps
- Remove stale kitty.conf.bak and untracked host fragments
