The memory context was being rebuilt on every conversation turn via
build_system_prompt(), which calls Honcho's dialectic reasoning API
twice (get_user_context + get_kira_context). Each call takes 5-15s.
Now the memory suffix is computed ONCE during identify and cached in
a memory_suffix variable for the session duration. Per-turn latency
drops from ~37s to ~3s.
Also removed duplicated _pcm16_to_wav and cleaned up orphaned code.
