Whitelist exceptions previously entered a 24h pending queue and were
promoted to approved by the enforce loop once the cooldown elapsed.
add_pending_exception now approves immediately, so the entire pending/
promote/cooldown mechanism is dead: drop WHITELIST_COOLDOWN_SECONDS,
PENDING_EXCEPTIONS_FILE, _load_pending/_save_pending,
promote_pending_exceptions, and list_pending_exceptions, plus the
enforce-loop promotion step and the CLI's now-empty pending display.
Usage text and docstrings updated to state exceptions are active
immediately. Tests for the removed machinery deleted; add-exception
tests assert immediate approval. Coverage remains 100%.
