What it does

Adds a focused WordPress semantic validator regression for wp_postmeta.post_id references. The fixture covers a source branch deleting a post while the target edits scalar and JSON postmeta rows that still point at that post.

Rationale

wp_postmeta.post_id is the ownership edge from metadata to its WordPress post. A row-level merge can preserve target metadata edits and apply the source post delete, but that leaves orphaned metadata unless a semantic validator reports the stale owner for review.

Implementation

The new discovered validator scans postmeta rows with post_id > 0, verifies the referenced post row still exists, and emits plugin-wp-postmeta-missing-post findings. The test asserts that the post delete remains staged, target scalar and JSON metadata edits remain visible, and plugin audit output identifies the missing post, stale post_id field, and JSON metadata row.

The merge reliability matrix now records postmeta owner coverage alongside existing post author, post parent, usermeta, menu, taxonomy, media, comment, and option reference coverage.
