DurableStateStore backed by MariaDB / MySQL (mariadb). Sibling of
PostgresDurableStateStore with the MariaDB dialect for the revision
CAS:
- create (expectedRevision 0): plain
INSERT; a duplicate-key error (1062) means the row already exists → conflict. - update (expectedRevision > 0):
UPDATE … WHERE revision = expected;affectedRows === 0means the stored revision diverged → conflict. (revision always changes, so a matched row always reports 1.)

Defined in: src/persistence/durable-state-stores/MariaDbDurableStateStore.ts:58
Upsert the state for persistenceId. expectedRevision must match the
current stored revision (0 when no record exists yet). Throws
DurableStateConcurrencyError on conflict. Optional options
carry per-call preferences from the caller (e.g. compression /
encryption set on the actor); stores that cannot honour them
silently ignore the field.
