/**
 * Append-side helpers for the compiler-owned SQL-trigger migration.
 *
 * Ported verbatim (behavior-for-behavior) from
 * `apps/compiler/src/utils/trigger-migration.ts`. Only the append half moves
 * to the CLI — `buildTriggerJournalMigration`, `renderSqlTrigger`, and
 * `loweredTriggerName` stay compiler-side because they run during
 * compilation, not during migration generation. The compiler still decides
 * WHAT the trigger migration says (`meta.triggerJournalMigration`); the CLI
 * only decides where and whether it lands.
 *
 * Keep `MIGRATION_HEADER`, the DROP composition, and the trigger-name regex
 * byte-identical to the compiler's copy — the content hash embedded in the
 * journal tag is computed over `createSql` upstream, but the composed
 * document is what gets applied, and a whitespace drift here would rewrite
 * an applied migration's bytes on the next compile.
