Playwright bun-sqlite compatibility

[kentcdodds]

Summary

This PR resolves issues preventing Playwright E2E tests from running by:

• Conditionally loading bun:sqlite and falling back to lru-cache when not running in Bun.
• Adding an SSR fallback in entry.server.tsx for environments where renderToPipeableStream is unavailable (e.g., Bun).
• Updating Playwright scripts to explicitly use bunx for execution.

Test Plan

Run bun run test:e2e:run to verify end-to-end Playwright coverage for SSR and core flows.

Checklist

• Tests updated
• Docs updated

Screenshots

Login page refresh renders cleanly with the Bun SSR fallback.

Note

Medium Risk
Touches SSR entrypoint wiring and the background text-sending cron runner (behavior intended to be the same but now lives in a new module), so regressions could impact page rendering or scheduled message delivery.

Overview
Updates server-side rendering to import renderToPipeableStream from react-dom/server.node and removes an unnecessary async Promise executor in entry.server.tsx, while also switching cron initialization to a new cron-runner.server.ts module.

Extracts the interval-based cron runner and sendNextTexts logic out of cron.server.ts (leaving only cron parsing/scheduling helpers), updates cron tests to target the new runner, and adjusts Playwright E2E scripts to run via bunx.

Removes the test global setup’s import of cache.server.ts, avoiding bun:sqlite-only code during Playwright/global setup execution.

• ✅ Fixed: Abort timeout cannot protect against hanging shell render
  • Scheduled the abort timeout immediately after creating the AbortController so hangs before shell readiness are protected.
