v0.1.0

Added

• lenient_guc audit parameter (default app.audit_lenient). When this GUC
  is 'true', audit_stamp tolerates a missing actor and leaves
  created_by / updated_by NULL instead of raising — the opt-in for bootstrap
  seeding, where a back-fill resolves the NULLs before the NOT NULL tighten.

Changed

• audit_stamp now refuses actor-less writes with a clear, named error. A
  write to an audited table with no actor GUC set previously landed created_by
  NULL and surfaced only as a bare NOT NULL violation (or silently, while the
  columns were still nullable). It now raises audit_stamp: <actor_guc> is not set; refusing to write to <schema>.<table> with a hint, so a forgotten
  session / service context fails loudly at the source. Bootstrap seeding opts
  out via the new lenient_guc (run the seed transactions with
  bootstrapSession: { 'app.audit_lenient': 'true' }).
