Re-enable p10k instant prompt (sudo-key ssh-add moved above it). Drop
oh-my-zsh.sh (second compinit, update check); set up what OMZ plugins
need ourselves. Cache java_home, go env, fzf --zsh output. Disable the
kubecontext segment (ran kubectl per shell). Log starts over 1 s to
~/.cache/zsh/startup-slow.log to catch cold-start stalls.

Move antidote update from every shell start to update_mac.sh: it dropped
the bundle cache each time, forcing a rebuild on the next start. Background
the locale write and skip the brew --repository fork.
