Optimize zsh startup time (~10x faster)

- Add compinit caching (regenerate daily instead of every shell)
- Set skip_global_compinit to avoid double initialization
- Remove kubectl from oh-my-zsh plugins
- Add lazy-loading for kubectl completions
- Add common kubectl aliases (k, kgp, kgs, kgn, etc.)

Startup time: 1.55s → 0.15s
