- subconscious.rs: use .get(fork_point..) instead of direct slice
to avoid panic when fork_point > entries.len()
- dmn.rs: batch all output injections (surface, reflection, thalamus)
under a single agent lock acquisition instead of three separate ones
- dmn.rs: use Store::cached() instead of Store::load() when rendering
surfaced memories
- Add scoring persistence analysis notes
