larssand bc4d2f465f Also veto timestamp-shaped fields from categorical/entity/relationship roles ...

Found live: a baseline-maintenance vacuum surfaced eventtime/timestamp
sitting in a stream's categorical_fields, hitting the max-values-per-field
cap at 2001 distinct values. Same failure mode as the original context
incident — a timestamp is near-unique on essentially every event, so
tracking it as a categorical or relationship field guarantees a "new"
finding every time. Extends _SHAPE_VETO (entity/categorical/relationship)
to also exclude "timestamp" shape, reusing the existing veto machinery and
its default 60-confidence threshold (timestamp classification isn't capped
low the way free_text is, so the stricter default applies correctly).
Existing profiles with this issue get flagged automatically via
detect_shape_mismatches, which already reuses the same veto check.
