From 891cca57f888b4c5414b16369ffdc259afb7b474 Mon Sep 17 00:00:00 2001 From: ProofOfConcept Date: Wed, 25 Mar 2026 00:52:41 -0400 Subject: [PATCH] merge poc-agent into poc-memory as agent/ module Eliminates the circular dependency between poc-agent and poc-memory by moving all poc-agent source into poc-memory/src/agent/. The poc-agent binary now builds from poc-memory/src/bin/poc-agent.rs using library imports. All poc_agent:: references updated to crate::agent::. poc-agent/ directory kept for now (removed from workspace members).
