feat(etc): template kernel cmdline, derive LUKS UUID from partition name
Prompt once at 'chezmoi init' time for the LUKS root partition (e.g.
nvme0n1p2) and store it under [data].luksRootPartition in the per-machine
chezmoi config. etc/kernel/cmdline.tmpl resolves the UUID at apply time
via lsblk, so reinstalls only require re-entering the partition name.
The etc deploy script now renders *.tmpl sources through
'chezmoi execute-template' and installs them without the suffix. The
resolved UUID is folded into the onchange hash so the script re-runs
when the UUID changes even if etc/ content is unchanged.
just etc-status/diff transparently handle .tmpl sources (strip suffix
for the live-path mapping, render before diffing). etc-re-add skips
.tmpl files since template sources can't be reverse-rendered from the
live file.
