fix: resolve undefined $agent_id and $job_snapshot in AIStep::executeStep()

[chubes4]

Summary

• $job_snapshot and $agent_id were defined in validateStepConfiguration() but referenced in the separate method executeStep() without being re-defined
• PHP treated both as null, which silently broke two things:
  1. Per-agent tool policies — ToolPolicyResolver received agent_id = 0, skipping all agent-specific tool filtering
  2. Per-agent model overrides — resolveModelForAgentContext() received null, always returning global defaults instead of agent-specific model config
• Also caused PHP Warning noise in debug.log every 5 minutes (Undefined variable $agent_id on lines 220/227)

Fix

Two lines added at the top of executeStep(), matching the exact pattern already used in validateStepConfiguration():

$job_snapshot = $this->engine->get( 'job' );
$agent_id     = (int) ( $job_snapshot['agent_id'] ?? 0 );

Impact

• Eliminates PHP Warning log noise
• Enables per-agent tool policies to actually apply during pipeline AI execution
• Enables per-agent model overrides to work in pipeline context
• No behavioral change for flows without agent-specific config (they already fall through to global defaults)
