Move bat cargo install from run_once_20 to run_onchange_30

Browse source 
run_once_20 runs BEFORE run_onchange_30 in the bootstrap chain, so
'command -v cargo' inside run_once_20 was always false on a fresh
box — cargo install bat was skipped, leaving bat missing on debian.

Move the bat install to run_onchange_30 (which runs last, after
rustup is installed). Restructure the script to:
1. Ensure cargo is installed (existing logic)
2. Install bat via cargo on debian only (new logic, gated by os_family)

This way the bootstrap chain becomes:
  run_once_00 -> run_once_10 -> run_once_20 (apt packages, neovim, oh-my-zsh, font)
  -> run_onchange_30 (rustup, then bat from crates.io)

Crouton currently has rustup installed but no bat (cargo install
in progress in background). Re-running chezmoi init will skip
run_once_20 (state recorded) and re-run run_onchange_30 (content
changed), which will see bat missing and trigger cargo install
automatically.
