Fix tier logging: capture actual_tier, fix parse_run_block regex, remove reply_text truncation

- Add tier_capture param to _run_agent_pipeline; append tier after determination
- Capture actual_tier in run_agent_task from tier_capture list
- Log tier in replied-in line: [agent] replied in Xs tier=Y
- Remove reply_text[:200] truncation (was breaking benchmark keyword matching)
- Update parse_run_block regex to match new log format; llm/send fields now None

Fixes #1, #3, #4

 # 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.
