v0.2.4 — agency_revisions tells the truth about what it is

agency_revisions advertised change_type values that the log never contained (field_changed, row_new); the real vocabulary is amended, row_absent, row_returned and the schema now says so as an enum. An unknown value is an explicit tool error. Rows carry id and cause_class; the response adds by_cause_class, log_covers_to, order, and the same observation-not-cause disclaimer the dataset ships. All six tool descriptions now state result shape, ordering and which sibling tool to use. Self-test 22/22 against live data.
