Zsh History Ignore Patterns

• Prefer programs.zsh.history.ignorePatterns for the pattern list in home/zsh/default.nix.
• HISTORY_IGNORE only filters when writing the history file; to prevent entries from being added at all, define a zshaddhistory hook.
• Ensure extended globbing is enabled (setopt EXTENDED_GLOB) and use [[ $1 != ${~HISTORY_IGNORE} ]] inside the hook.
• The patterns use extended glob syntax like ls#( *)#, so keep setopt extendedglob within the hook as well.
• To disable extended globbing in the current shell session, run unsetopt EXTENDED_GLOB.
• In Nix multi-line strings (like initContent), escape zsh variables as ''${VAR} to avoid Nix interpolation, e.g. ''${HISTORY_IGNORE:-}.
• zshaddhistory receives the command line with a trailing newline; strip it (e.g. local line=''${1%%$'\n'}) before matching ignore patterns.
• If ignored commands still show on Up/Down, clear in-memory history with history -c then reload with fc -R.
