Greptile SummaryThis PR currently adds an unrelated Git-exclusion test file rather than the described ACP transcript fix.
Confidence Score: 3/5The PR is not safe to merge because the added test cannot resolve its imported module and the intended ACP fragmentation fix is absent. The only changed file introduces a test-collection/typechecking failure while neither changing ACP production behavior nor adding the described ACP regression coverage.

### Issue 1
apps/emdash-desktop/src/core/features/projects/node/ensure-emdash-excluded.test.ts:4
**Imported Module Is Missing**
This test imports `./ensure-emdash-excluded`, but that sibling module does not exist in the repository. Because the desktop Node test project includes this file, module resolution fails during typechecking or test collection and blocks the merge checks.
### Issue 2
apps/emdash-desktop/src/core/features/projects/node/ensure-emdash-excluded.test.ts:73-148
**ACP Fix Is Absent**
The PR is intended to prevent ACP transcript fragmentation, but every added test exercises Git exclusion behavior instead. No ACP reducer or parser behavior is changed or covered, so interleaved tool events retain the existing fragmentation behavior and the reported issue remains unfixed.

Description
Fix ACP streamed assistant messages being incorrectly split into multiple transcript messages when tool events are interleaved between
agent_message_chunkevents without amessageId.Tool calls, tool updates, and plan events no longer close an open synthesized assistant segment. This keeps subsequent message chunks attached to the same logical assistant response while preserving existing behavior for explicit message IDs.
Added regression coverage for consecutive chunks, interleaved tool events, Markdown spanning chunks, and explicit message ID behavior.
Related issues
Fixes #3166.
Testing
messageIdassistant chunks remain a single transcript message across tool events.Screenshot/Recording (if applicable)
Not applicable — this is a backend/reducer behavior fix with regression tests.
