Root cause rozbitého CI: docker CLI v jobu mluví s hostovským daemonem,
takže -v bind mounty checkoutu ukazovaly na neexistující hostovské cesty
→ flyway dostal prázdné adresáře (applied migration not resolved locally).
Fix: docker create + docker cp (streamuje od klienta) + start/wait/logs.
Cíl /sql, ne /flyway/sql — image tam deklaruje VOLUME, který by kopii zastínil.
