fix(memory): convert update_memory script to CommonJS and add ls fallback

Renames update_memory.mjs to update_memory.js and converts from ESM
to CommonJS (require) so the script works without "type":"module" in
user projects.

Adds a fallback ls instruction outside <aidd_project_memory> in AGENTS.md
template so agents can discover memory files if the hook did not run.
