- Relocated compaction, branch-summarization, pruning, and utils from coding-agent to packages/agent/src/compaction. - Moved OpenAI remote compaction helpers from packages/ai to the new compaction module. - Added handoff.ts with extractHandoffDocument, createHandoffContext, and renderHandoffPrompt helpers. - Exposed new entries.ts with standalone SessionEntry types so coding-agent no longer owns them.
