fix: resolve multiple bugs in .zshrc

- Move HISTFILE from XDG_CACHE_HOME to XDG_STATE_HOME (history is
  state, not cache — cache cleaners could delete it)
- Fix compinit: add -d flag to put zcompdump in XDG_CACHE_HOME
  instead of polluting $HOME
- Fix cdr: set recent-dirs-file to XDG_STATE_HOME location
- Fix ZSH_HIGHLIGHT_HIGHLIGHTERS/STYLES: set BEFORE sourcing the
  plugin (required by plugin docs)
- Fix zsh-history-substring-search: bind to Up/Down keys (was loaded
  but never bound — dead code)
- Remove dead .../..../….. aliases (rationalise-dot widget intercepts
  every dot keystroke, making these unreachable)
- Remove redundant ShiftTab reverse-menu-complete binding (overridden
  by autosuggest-accept)
