Previous workflow applied only 049_delegations.up.sql — fragile to
future migrations that touch the delegations table or any other
handlers/-tested table. Operator would have to remember to update
the workflow's psql -f line per migration.
New behavior: loop every .up.sql in lexicographic order, apply each
with ON_ERROR_STOP=1 + per-migration result captured. Failed migrations
are SKIPPED rather than blocking the suite — handles the historical
migrations (017_memories_fts_namespace, 042_a2a_queue, etc.) that
depend on tables since renamed/dropped and can't replay from scratch.
Migrations that DO succeed land their tables, which is sufficient for
the integration tests in handlers/.
Sanity gate at the end: if the delegations table is missing after the
replay, hard-fail with a loud error. That catches a real regression
where 049 itself becomes broken (e.g., schema rename), separate from
the historical-broken-migration noise above.
Per-migration log line ("✓" or "⊘ skipped") makes it easy to spot
when a migration that SHOULD have replayed didn't.
Verified locally: full migration chain runs, 049 lands, all 7
integration tests pass against the chained-migration DB.
Closes#320.
