fix: ntfy ping is her personal text to Brian, by her decision — not a thought dump

Feedback: the push broadcast her raw internal thought ("Eelis Parssinen's
victory is a reminder...") — read like a journal entry, not her texting him.

Now the flow matches the intent: she thinks/journals, then *decides* "I should
tell Brian about this." think() asks for an optional `reach_out` — a real text
message addressed TO him in her own voice, written only when she chooses to. The
ping sends that message (title "Lyra", like a text from her), never the internal
thought. No reach_out = nothing sent (most thoughts stay hers).

- Pinging decoupled from the salience score: her decision (a reach_out) drives it,
  not a threshold. PING_SALIENCE is now an optional floor (default 0.0).
- Defensive: reject the placeholder echo ("reach_out"), too-short junk, or the
  thought pasted back as the message.
- notify.push: title now optional (omitted -> cleaner text-style notification).

Verified live: 3 passes kept private; a decided reach-out lands as a personal
text. Suite 67 green, ruff clean.
