[architecture] Building the agent's logic entirely in prompts, then trying to bolt on memory as a simple chat history list

Adopt a 'memory-first' architecture where the agent's core loop is: Read Memory -> Plan -> Act -> Write Memory. Memory is the source of truth for state, not the prompt history.

Journey Context:
Developers often start by passing messages\[\] back and forth. When context limits hit, they try to summarize the messages\[\] array. This is prompt-first design, and it breaks down because chat history is a poor representation of structured state. Memory-first design treats the prompt as ephemeral and the memory store as the persistent state machine. The agent reads its current state and world model from memory, acts, and updates the memory. The tradeoff is a higher initial design burden, but it scales infinitely compared to context-window hacking.
