* test(perf): measure the serial IPC depth before the J1 first card Adds renderer.ipcSerialDepthToFirstCard to the launch journey: the length of the longest chain of bridge calls in which each call started after the previous one completed, among calls that completed before the first card. The main IPC capture now records the ordered start/completion timeline; the depth, its lower bound, the chain and the timeline are per-iteration evidence, and the CI job summary prints the chain. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * test(perf): keep the IPC timeline consistent around the J2 start marker A call that started before the start marker no longer records its completion in the timeline, and completions of a method with calls in flight both inside and outside the timeline are attributed outside and counted, instead of skipping the first marker-method completion.

Runs `pnpm run perf:journeys` under xvfb on an Ubuntu runner, writes the
|
|
measurements to the job summary and returns the path of the summary.json
|
|
it wrote. Callers check out, set up pnpm and Node, install dependencies
|
|
and upload what they need. Contract: docs/architecture/performance-journeys.md.
