Andrejus ffd26e06d6 perf(zsh): cache tool init, lazy-load, remove plugins ...

Startup: 150ms → 40ms (native), projected 10-30s → <1s (iSH)

- Cache mise/fzf/zoxide init output keyed on binary mtime
- zcompile all sourced files to bytecode at install time
- Lazy-load compinit (first Tab), fzf+widgets (first keystroke)
- Remove autosuggestions and syntax-highlighting plugins
- Switch mise to shims mode (no per-prompt hook)
- Conditional mkdir (skip if dirs exist)
- Remove TRAPINT/flash handler, cache session info
- Eliminate per-prompt subshell forks (REPLY pattern)
