soul loop-1: identity loading, boot counter, internal state events, richer awareness

- memory.el: mem_boot_count_get/inc (persisted counter), mem_emit_state_event (InternalStateEvent schema)
- soul.el: load_identity_context() loads intel-dna/values/mem-philosophy nodes into state at boot; boot counter incremented on every startup
- awareness.el: attend() gains search/activate/strengthen/forget action types; one_cycle() emits InternalStateEvent for non-trivial decisions
- chat.el: build_system_prompt includes [IDENTITY GRAPH] block from graph-loaded context; handle_chat strengthens activated nodes after each turn
