/**
* @return list<string> Table names referenced by `Schema::` calls
* in the given migration file contents. Empty
* when nothing matches — callers treat that
* as "fall back to the broad watch pattern".
* OR raw DDL statements in the given migration
* file contents. Empty when nothing matches —
* callers treat that as "fall back to the
* broad watch pattern".
*
* Two passes:
* 1. `Schema::create|table|drop|dropIfExists|dropColumn[s]|rename`
* captures the conventional Laravel migration shape.
* 2. Raw DDL fallback: scans for `CREATE / ALTER / DROP /
* TRUNCATE / RENAME TABLE <name>` patterns inside string
* literals (i.e. `DB::statement('CREATE TABLE …')`,
* `DB::unprepared('ALTER TABLE …')`). False positives possible
* if the same syntax appears in a comment or unrelated string,
* but over-attribution is correctness-safe.
