fix: add retry logic to npm ci for Windows CI flakiness (#2657)

## Summary - Windows CI builds intermittently fail during `npm ci` with `EBUSY`/`EPERM` errors caused by file locking (antivirus, indexing services) - Added a 3-attempt retry loop with 10s delay and `node_modules` cleanup between attempts - Applied to both the `build` and `e2e-tests` jobs in the CI workflow ## Test plan - [x] Lint passes - [x] Type checks pass - [x] Unit tests pass (810/810) - Verify the next Windows CI run completes the `npm ci` step successfully #skip-bugbot 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- ## Summary by cubic Add retry logic to npm ci on Windows runners to handle intermittent EBUSY/EPERM file locks. This stabilizes the build and e2e-tests jobs. - **Bug Fixes** - Retry npm ci up to 3 times with a 10s delay. - Clean node_modules between attempts. - Implemented via scripts/npm-ci-retry.sh and applied to both build and e2e-tests jobs. <sup>Written for commit 79bc6ede3b90db4068369e59853144170547aaf0. Summary will update on new commits.</sup>   --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2657" 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>  --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
