Function applyRuntimeFirewallRules

applyRuntimeFirewallRules(
    firewallState: RuntimeFirewallState,
    config: GuardConfig,
    napplet: string,
): void
Install the guard profile's rates for an applet in the runtime firewall.

The runtime's firewall runs before every dispatch, including the envelopes kernl held for a hidden window and released later, so the profile's limits are pushed into it when a window mounts and again when the profile changes. No policy is set: kehto's allow policy bypasses every rate, matcher and burst check, and the user's choices to deny or block live in the grants layer, not here.
Parameters
- firewallState: RuntimeFirewallState
  bridge.runtime.firewallState.
- config: GuardConfig
  Current guard configuration.
- napplet: string
  Applet identity (dTag).
Returns void
Nothing; the firewall state is mutated and persisted.
Example
```
applyRuntimeFirewallRules(bridge.runtime.firewallState, guardConfig, summary.identity.dTag);
```
