fix: honor PORT injected by af run (unbreak install-and-run)

[AbirAbbas]

Problem

af run pr-af fails its readiness check:

❌ Failed to run agent: agent node failed to start: agent node did not become ready within 10s

pr_af/app.py calls app.run(port=8004, host="0.0.0.0") with a hardcoded port. The SDK treats an explicitly-passed port as the highest-priority override, so it ignores the PORT environment variable the AgentField runner injects after it allocates a free port. The node binds 8004 while the CLI polls the port it assigned (e.g. 8001), so the health poll never sees the node and times out.

The other agent nodes (sec-af, cloudsecurity-af) already read PORT and run fine on af run; pr-af was the only one hardcoding it.

Fix

app.run(port=int(os.getenv("PORT", "8004")), host="0.0.0.0")

Honors the runner-injected PORT, keeps 8004 as the standalone default (python -m pr_af.app). os is already imported.

Verification

Installed the patched node and launched it directly with PORT=8011:

ℹ️ Starting agent node 'pr-af' on port 8011
INFO:     Uvicorn running on http://0.0.0.0:8011
$ curl localhost:8011/health → {"node_id":"pr-af", ...}

Pre-fix it bound 8004 regardless of PORT.
