Subject: [PATCH] Whitelist terminal identity and pager env vars

Without TERM_PROGRAM/TERM_PROGRAM_VERSION, Claude Code and similar TUIs
can't detect the host emulator and lose capability-gated features like
Shift+Enter. Also pass through LS_COLORS, LESS*, MANPAGER, MANPATH, etc.
so interactive UX matches the host.
