Fix benchmark log extraction: first tier match, increase log tail to 300

- Remove reversed() from extract_tier_from_logs: first match = routing decision
  (dry-run complex logs tier=complex early, then overwrites with tier=medium at done)
- Increase log tail from 80→300 to handle concurrent log activity

Fixes #7, #10

 # Agent Pipeline Rules
 
 ## Tiers
-- Complex tier requires `/think ` prefix. Any LLM classification of "complex" is downgraded to medium. Do not change this.
-- Medium is the default tier. Light is only for trivial static-knowledge queries matched by regex or LLM.
+- Routing is fully automatic: router classifies into light/medium/complex via 3-way embedding similarity.
+- Complex tier is reached automatically for deep research queries — no prefix required.
+- Medium is the default tier. Light is only for trivial static-knowledge queries matched by regex or embedding.
 - Light tier upgrade to medium is automatic when URL content is pre-fetched or a fast tool matches.
+- `tier_override` API parameter still allows callers to force a specific tier (e.g. `adolf-deep` model → complex).
 
 ## Medium agent
 - `_DirectModel` makes a single `ainvoke()` call with no tool schema. Do not add tools to the medium agent.

 # LLM Inference Rules
 
-- All LLM calls must use `base_url=BIFROST_URL` with model name `ollama/<model>`. Never call Ollama directly for inference.
+- All LLM calls must use `base_url=LITELLM_URL` (points to LiteLLM at `host.docker.internal:4000/v1`). Never call Ollama directly for inference.
 - `_reply_semaphore` (asyncio.Semaphore(1)) serializes all GPU inference. Never bypass it or add a second semaphore.
-- Model names in code always use the `ollama/` prefix: `ollama/qwen3:4b`, `ollama/qwen3:8b`, `ollama/qwen2.5:1.5b`.
-- Timeout values: router=30s, medium=180s, complex=600s. Do not reduce them — GPU inference under load is slow.
-- `VRAMManager` is the only component that contacts Ollama directly (for flush/prewarm/poll). This is intentional — Bifrost cannot manage VRAM.
+- Local Ollama models use the `ollama/` prefix: `ollama/qwen3:4b`, `ollama/qwen2.5:1.5b`. Remote models (e.g. OpenRouter) use their full LiteLLM name: `openrouter/deepseek-r1`.
+- Timeout values: router=30s, medium=180s, complex=600s. Do not reduce them.
+- `VRAMManager` is the only component that contacts Ollama directly (for flush/prewarm/poll). This is intentional — LiteLLM cannot manage VRAM.
+- Complex tier uses a remote model (`DEEPAGENTS_COMPLEX_MODEL`) — no VRAM management is needed for it.
