The Provenance enum couldn't represent agents defined outside the source code. Replace it with a Text field in the capnp schema so any agent can write its own provenance label (e.g. "extractor:write", "rename:tombstone") without a code change. Schema: rename old enum fields to provenanceOld, add new Text provenance fields. Old enum kept for reading legacy records. Migration: from_capnp_migrate() falls back to old enum when the new text field is empty. Also adds `poc-memory tail` command for viewing recent store writes.
