Function tryCompactOnExit

coderd/x/chatd/chatloop/chatloop.go:1803–1829

tryCompactOnExit runs compaction when the chatloop is about to exit early (e.g. via ErrDynamicToolCall). The normal inline and post-run compaction paths are unreachable in early-exit scenarios, so this ensures the context window doesn't grow unbounded.
