Deploying a Release

Announce at start: "Using pythia-deploy — previewing every statement in the release first."

Phase: Ask → Do — the whole ordered set is previewed and approved once, then run step by step

A release script run with sqlplus @release.sql has no snapshot, no preview, no verify and no record of what landed before line 212 failed. pythia deploy runs the same file through the write path, statement by statement, so a failure stops cleanly with an exact list of what landed and how to undo it.
