"""Outbound push so Lyra can reach Brian when he's not in the app (ntfy).

This is the literal version of what she asked for — thinking "unprompted, without
you" only matters if she can also *reach* you. When a thought tugs hard enough,
the thought loop calls `push()` here and it lands on your phone with a tap-through
to the Thoughts feed. One-way: you reply in the app, which feeds the loop.

Transport only. Whether/when to ping (salience bar, cooldown, quiet hours) is the
thought loop's call — see `thoughts.maybe_ping`.
