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.

+# JdbcChatMemoryRepository on PostgreSQL 16
+
+Table created by initialize-schema=always:
+  conversation_id  character varying            (36)
+  content          text                         
+  type             character varying            (10)
+  timestamp        timestamp without time zone  
+  sequence_id      bigint                       
+
+After one call, rows for the conversation:
+  seq=0  USER      My name is Priya
+  seq=1  ASSISTANT Nice to meet you, Priya.
+
+New repository + new memory over the same database, then "What is my name?":
+  reply: Your name is Priya.
+  findConversationIds() returns every conversation in the table: [6f0a1c9e-2b7d-4c55-9a53-0d1f3e7a2b10]
