Adds a per-reaction long-press callback to StreamMessageItem and StreamMessageListView, reporting the message's BuildContext and a ReactionLongPressDetails so apps can open a reactions sheet. Left null, the chips register no long-press gesture, so the message's own long-press handling (the actions modal) keeps working as before. Points stream_core_flutter at a local path dep for the matching core change; swap back to a git ref before merging. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The chips sit inside the message row's own long-press InkWell, so both recognizers compete. Assert the chip wins when onReactionLongPress is set, and that the message long press still fires when it is not. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The chips now always claim the long press and open the detail sheet pre-filtered to that reaction, rather than falling through to the message actions modal. Tap gets the same pre-filtering. Rewrites the long-press tests around the new contract and documents the behaviour change in the changelog. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Describe the unfiltered fallback for grouped chips.
Line 10 is inaccurate for clustered and overflow chips. Those chips resolve to null, so ReactionDetailSheet opens without an initial reaction filter.
State that pre-filtering applies only when the chip maps to a single reaction.
