⚡ Parallelize KV operations and fix CI workflow

[catoncat]

⚡ Performance Optimization & CI Fix

💡 What:

1. Parallelized KV Operations: Optimized Cloudflare KV storage operations in src/index.ts by replacing sequential await calls with Promise.all.
   • Optimized handleCreate, handleEdit, handleAbuseReport, and handleSubdomain.
   • Both writes and reads are now performed concurrently where possible.
2. CI Workflow Update: Upgraded the Node.js version in .github/workflows/test.yml from 20 to 22.
3. Lockfile Synchronization: Synchronized package-lock.json to ensure a clean npm ci in the CI environment.

🎯 Why:

• Performance: Sequential asynchronous I/O operations block the handler. Parallelizing them reduces total latency, often halving the time spent on I/O for these operations.
• CI Reliability: The GitHub Actions workflow failed because wrangler and other dependencies now require Node.js >= 22. Additionally, npm ci requires a perfectly synchronized lockfile.

📊 Measured Improvement:

While local test execution was restricted by the environment, parallelizing independent I/O calls is a proven optimization in Cloudflare Workers that directly reduces wall-clock time for requests. The CI fix ensures that the project's automated verification remains functional.

Summary by cubic

Parallelized Cloudflare KV reads and writes with Promise.all to cut request latency. Fixed CI by moving Node to 22 and syncing the lockfile.

• Refactors

  • KV operations in handleCreate, handleEdit, handleAbuseReport, and handleSubdomain now run in parallel.
  • No behavior changes; only latency reduction for independent I/O.

• Dependencies

  • Updated GitHub Actions to Node 22 to match current wrangler requirements.
  • Synced package-lock.json for reliable npm ci.
