Add tmux resurrect defaults to rebuilt images

Browse source 
New VMs should come up with tmux session persistence ready instead of requiring per-VM plugin setup, and rebuilt images should stop carrying stale Docker installer scraps.

Configure both image build paths to install TPM, tmux-resurrect, and tmux-continuum for root, manage a marked /root/.tmux.conf block with autosave enabled and restore left manual, and remove legacy get-docker helper files during provisioning.

Update the README and repo guidance to document the rebuilt-image behavior. Verified with bash -n customize.sh, GOCACHE=/tmp/banger-gocache go test ./internal/daemon -run TestBuildProvisionScriptInstallsDefaultTools, and GOCACHE=/tmp/banger-gocache make build.
