release: v3.5.5

OpenCode 1.2.0+ changed reasoning-delta and text-delta to emit
'message.part.delta' instead of 'message.part.updated'. Without
handling this event, lastUpdate was only refreshed at reasoning-start
and reasoning-end, leaving a gap where extended thinking (>3min)
could trigger stale timeout.

Accept both event types as heartbeat sources for forward compatibility.

+- NEVER use em dashes (—) or en dashes (–). Use commas, periods, ellipses, or line breaks instead. Zero tolerance.
+- Remove AI-sounding phrases: "delve", "it's important to note", "I'd be happy to", "certainly", "please don't hesitate", "leverage", "utilize", "in order to", "moving forward", "circle back", "at the end of the day", "robust", "streamline", "facilitate"

+- Use contractions naturally: "don't" not "do not", "it's" not "it is".
+- Vary sentence length. Don't make every sentence the same length.
+- NEVER start consecutive sentences with the same word.
+- No filler openings: skip "In today's world...", "As we all know...", "It goes without saying..."
