feat(journal-ksqlite): add :journal-ksqlite module with KsqliteJournalStore implementation
ci / JVM build + tests (push) Failing after 1m10s
ci / JVM build + tests (push) Failing after 1m10s
- Introduced a new `:journal-ksqlite` module implementing `:journal-api` with Ksqlite backend. - Added a minimal schema (message table + 1 index) for append-only audit logs, eliminating modifications and ensuring immutable storage. - Provides `KsqliteJournalStore` for appending, listing, and clearing messages with JSON-encoded payloads. - Autonomous schema migration (`Schema.migrate`) and in-memory tests validate functionality. - Partial duplication of `:storage-ksqlite/KsqliteMessageStore`; consumers will transition gradually.

|

* ksqlite-реализация [MutableJournalStore] (append-only audit log).
|
||||
*
|
||||
* Структура — копия [pw.binom.agentik.storage.ksqlite.KsqliteMessageStore]
|
||||
* из `:storage-ksqlite`, но:
|
||||
* - лежит в собственном модуле `:journal-ksqlite`;
|
||||
* - реализует переименованный [MutableJournalStore] (раньше был
|
||||
* `MutableMessageStore`, теперь главный класс — `JournalStore` /
|
||||
* `MutableJournalStore`); сам тип записи [MessageRecord] не
|
||||
* переименовывался.
|
||||
*
|
||||
* Prepared statements (insert / list / clear) препарируются один раз в
|
||||
* конструкторе и закрываются в [close]. Без этого GC финалайзеры каждого
|
||||
* StmtHolder'а пытаются `sqlite3_finalize` stmt, чей parent connection уже
|
||||
* закрыт → SIGSEGV в `pthread_mutex_lock` (см. [pw.binom.db.ksqlite.StmtHolder]).
|
||||
*
|
||||
* `payloadJson` хранит JSON-сериализованные kind-specific поля. encoding
|
||||
* helpers (`encodeRecord` / `toMessageRecord` / `CallPayload` / ...) лежат
|
||||
* в [MessageCodecs.kt] рядом.
|
||||
*
|
||||
* ВНИМАНИЕ: `:storage-ksqlite/KsqliteMessageStore.kt` остаётся на диске —
|
||||
* это копия, не замена. Не удалять старый файл; миграция consumers'ов —
|
||||
* отдельно.
