BoolishTimestamp defaulted unrecognized non-empty values to true: any word it does not understand (a misspelling, "disabled", "banana") behaved as on. Unrecognized values are now valid+false with the error retained so callers can apply their own policy, and "disabled"/"disable" are no longer true-like. Both bool types now read the human "not supplied" set through one shared isBoolNull sentinel: empty/whitespace-only, the exact PG dump sentinel \N (case-sensitive), and the case-insensitive words null, \null, none, unknown. Bool previously reached absent only by ParseBool failing; it now matches BoolishTimestamp explicitly. Free-text types must not reuse this set: most of these words are legitimate values there.
