Makes the deployment path explicit in Task 1: traces the existing
lifespan → get_user_store → initialize_schema → conn.execute(SCHEMA_SQL)
flow, notes that the DO $$/IF NOT EXISTS pattern is the same one
every post-v1 column migration uses, and explains why rollback is
safe (additive changes only).
Adds two new verification steps to Task 1:
- Step 7: post-deploy psql checks against staging
- Step 8: same against production
Adds a "Post-deploy schema verification" block to CHECKLIST.md so
the schema state is verified after every server restart against
each target environment.
