fix: enable workers.dev subdomain after deployment

- Add enableSubdomain() method to CloudflareDeployer
- Call enableSubdomain() after worker deployment
- Use POST method to enable subdomain (not PUT)
- Increase retry404 from 0 to 5 for propagation delays
- Requires Workers Scripts:Edit permission on API token

This fixes the issue where deployed workers weren't accessible
on workers.dev due to subdomain not being enabled.
