Replace transformWithEsbuild with transformWithOxc for zero-coverage generation. OXC is bundled inside Vite via Rolldown so no extra package is needed. OXC does not constant-fold process.env.NODE_ENV without an explicit define, preserving all branches in the zero-coverage map. Reverts the esbuild direct dependency added in v1.5.1. Bumps version to 1.5.2. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Replace transformWithEsbuild with transformWithOxc for zero-coverage
generation. Pass jsx:{runtime:'automatic'} to force JSX transformation
regardless of the project's tsconfig.json — Next.js projects typically
set "jsx":"preserve" which OXC respects when auto-discovering tsconfig,
producing far fewer statements without this override.
