- ## Phase 1: Architecture & Maintainability (Refactoring)
--- [ ] **Extract LLM Call & Retry Logic:** Refactor `runLLMIteration` by moving the LLM calling, fallback chain, and context window retry logic into a dedicated method (e.g., `executeLLMWithRetry`).
--- [ ] **Extract Tool Execution Logic:** Refactor `runLLMIteration` by moving the parallel tool execution (`sync.WaitGroup`), channel routing, and async callbacks into a dedicated method (e.g., `executeToolBatch`).
--- [ ] **State Machine / Explicit Flow:** Clean up the main loop logic to reduce nested `if/for` blocks and make the transition between generating, executing tools, and compressing context more explicit.

- ## Phase 2: Reliability & Error Handling
--- [ ] **Graceful Recovery on Tool Panic:** Add `defer recover()` inside the parallel tool execution goroutines to prevent a panicked tool from crashing the entire `AgentLoop`. Return the panic as an error string to the LLM.
--- [ ] **Exponential Backoff:** Replace the linear backoff in LLM retries (`time.Duration(retry+1) * 5 * time.Second`) with exponential backoff and jitter to better handle rate limits.
