# talkto.py — Async Router for HAZE + CLOUD
#
# Unified async interface:
# - Default: HAZE only (fast, autonomous)
# - /cloud: Toggle CLOUD mode (pre-semantic sonar)
# - /stats: Show bridge statistics
#
# Design principle: HAZE IS ALWAYS AUTONOMOUS
# - CLOUD is optional enhancement
# - Silent fallback if CLOUD fails
# - No errors leak to user
#
# "Two minds that can resonate together,
#  but never depend on each other."

    Async router that orchestrates HAZE and CLOUD.
