Add chat-memory module: MessageWindowChatMemory, JDBC and Redis repositories, per-user conversation IDs

Real PostgreSQL 16 and Redis Stack 7.4; 24 tests write output/01-24. Covers the 20-message
default window with no property, the 36-character conversation_id, tool messages dropped by
JdbcChatMemoryRepository, concurrent add() on one conversation, a 1.x table under the 2.0
repository, the Redis repository silently backing off for a custom ChatMemory, and the
removal of PromptChatMemoryAdvisor.
