ecto - chore: upgrade GitHub Actions (breaking)

[jaredwray]

Summary

Upgrade GitHub Actions with major version bumps for Node 24 runtime and Wrangler v4 support.

Versions

• codecov/codecov-action v5 → v6 (Node 24 runtime requirement — already satisfied)
• cloudflare/wrangler-action v3 → v4 (defaults to Wrangler v4; pages deploy command unchanged)

Tests

• Workflow YAML parses correctly

Breaking notes

• codecov-action@v6 requires Node.js 24 on the GitHub Actions runner (mandatory after June 2, 2026)
• wrangler-action@v4 defaults to Wrangler CLI v4; no input changes needed for pages deploy usage
