Subject: [PATCH] Speed up shell startup: remove duplicate compinit, lazy-load
 pyenv/nvm

- Remove manual compinit in .zshrc (oh-my-zsh already handles it),
  eliminating a redundant ~350ms call
- Lazy-load pyenv init (~710ms) until first use, matching the existing
  kubectl lazy-load pattern
- Lazy-load nvm init for when it gets installed in the future
