Announcing Firewall Rules

What this post added

Introduced Firewall Rules, a new feature allowing customers to create custom rules based on multiple HTTP request attributes (e.g., IP address, User-Agent, Threat Score, AS Number) using a Wireshark-inspired expression language. This enables flexible and granular traffic control, including pattern matching with regular expressions, and supports both positive (allowlist) and negative (blocklist) security models. New actions like 'allow' were added, and the `cf.client.bot` field was introduced to identify known good bots.
