ci: use 2 e2e shards for self-hosted Mac mini runners (#2606)

## Summary - Update CI workflow to use 2 E2E test shards instead of 1 for self-hosted Mac mini runners (privileged authors) - This improves E2E test parallelism on self-hosted infrastructure ## Test plan - CI should run with 2 shards on self-hosted runners for privileged authors - Non-privileged authors still get 4 shards on GitHub-hosted runners (unchanged) 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2606" target="_blank"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://static.devin.ai/assets/gh-open-in-devin-review-dark.svg?v=1"> <img src="https://static.devin.ai/assets/gh-open-in-devin-review-light.svg?v=1" alt="Open with Devin"> </picture> </a>   --- ## Summary by cubic Run E2E tests in 2 shards on self-hosted Mac mini (macOS ARM64) runners for privileged authors to improve parallelism and speed up CI. Non-privileged authors remain on GitHub-hosted runners with 4 shards; other CI settings are unchanged. <sup>Written for commit 972f36eb853a620a3f08ac2089d725768177beb7. Summary will update on new commits.</sup>   --- > [!NOTE] > **Low Risk** > Low risk workflow-only change; main impact is CI execution behavior (more parallel shards) and potential shard/merge configuration issues if assumptions about 1 shard were relied on. > > **Overview** > In `.github/workflows/ci.yml`, increases **self-hosted privileged-author** Playwright E2E parallelism by changing the matrix from `1/1` to `2` shards (`e2e_shard=[1,2]`, `e2e_shard_total=[2]`). > > GitHub-hosted macOS/Windows runs remain at `4` shards, and build/job wiring is otherwise unchanged. > > <sup>Written by [Cursor Bugbot](https://cursor.com/dashboard?tab=bugbot) for commit 972f36eb853a620a3f08ac2089d725768177beb7.
