Supersedes the v0.51.199 proximity-re-pin (#3330) and the #3250 upward-intent timeout with a sticky-unpin model (ChatGPT/Claude/Codex behavior): scroll up = stay put until you return to the bottom or click the scroll-to-bottom control. Reconciled against the shipped #3330 code: removed the now-dead _recentMessageUpwardIntent reference from the #3319 rAF retry, kept the load-time -Infinity intent-init fix, kept the pinned-only >500 catch-up.

"""Regression: sticky manual unpin during streaming (supersedes #3250 timeout tuning).

After the user scrolls up to read earlier content, streaming tokens, tool cards,

and layout growth must not re-pin the viewport until the user scrolls back to

the bottom or clicks the scroll-to-bottom control.
