Align acTools config with actual tool availability.
Problem
AgentConfig.acTools is informational only; actual tools are controlled by
SeqConfig. This can drift and mislead observers.
Requirements
- Either enforce tool allowlist using acTools, or remove acTools from config
- Ensure config reflects real tool availability
Acceptance
- Tool availability in config matches runtime tool set
- Observability shows correct tool list
Added resolveAgentTools helper to align AgentConfig.acTools with actual Seq tools (allowlist semantics), wired CLI and op-runner to use it, and added a unit test.
