======================================

A scheduled daily briefing skill that reads:
    - your calendar (today + tomorrow)
    - the wiki (open commitments)
    - any inbox / message-queue you wire in

… and sends a single message to your phone every morning.

This is the killer use case our example user, Avery Stone, runs. The point
is not the AI — it is the *consistency*. A briefing every morning, at
the same time, that is grounded in your actual context.

This file is deliberately a *stub* — you fill in the connectors that
match your stack. The shape is what teaches.

Schedule with cron:
    0 6 * * *  cd /home/you/nanoclaw && .venv/bin/python daily_briefing.py
