feat(config): wire Big Brain provider into Hermes config (#574)

Add RunPod Big Brain (L40S 48GB) as a named custom provider:
- base_url: https://8lfr3j47a5r3gn-11434.proxy.runpod.net/v1
- model: gemma3:27b
- Provider name: big_brain

Usage:
  hermes --provider big_brain -p 'Say READY'

Pod 8lfr3j47a5r3gn, deployed 2026-04-07, Ollama image.

Closes #574

+# Research: Long Context vs RAG Decision Framework
+
+**Date**: 2026-04-13
+**Research Backlog Item**: 4.3 (Impact: 4, Effort: 1, Ratio: 4.0)
+**Status**: Complete
+
+## Current State of the Fleet
+
+### Context Windows by Model/Provider
+| Model | Context Window | Our Usage |
+|-------|---------------|-----------|
+| xiaomi/mimo-v2-pro (Nous) | 128K | Primary workhorse (Hermes) |
+| gpt-4o (OpenAI) | 128K | Fallback, complex reasoning |
+| claude-3.5-sonnet (Anthropic) | 200K | Heavy analysis tasks |
+| gemma-3 (local/Ollama) | 8K | Local inference |
+| gemma-3-27b (RunPod) | 128K | Sovereign inference |
+
+### How We Currently Inject Context
+1. **Hermes Agent**: System prompt (~2K tokens) + memory injection + skill docs + session history. We're doing **hybrid** — system prompt is stuffed, but past sessions are selectively searched via `session_search`.
+2. **Memory System**: holographic fact_store with SQLite FTS5 — pure keyword search, no embeddings. Effectively RAG without the vector part.
+3. **Skill Loading**: Skills are loaded on demand based on task relevance — this IS a form of RAG.
+4. **Session Search**: FTS5-backed keyword search across session transcripts.
+
+### Analysis: Are We Over-Retrieving?
+
+**YES for some workloads.** Our models support 128K+ context, but:
+- Session transcripts are typically 2-8K tokens each
+- Memory entries are <500 chars each
+- Skills are 1-3K tokens each
+- Total typical context: ~8-15K tokens
+
+We could fit 6-16x more context before needing RAG. But stuffing everything in:
+- Increases cost (input tokens are billed)
+- Increases latency
+- Can actually hurt quality (lost in the middle effect)
+
+### Decision Framework
+
+```
+IF task requires factual accuracy from specific sources:
+    → Use RAG (retrieve exact docs, cite sources)
+ELIF total relevant context < 32K tokens:
+    → Stuff it all (simplest, best quality)
+ELIF 32K < context < model_limit * 0.5:
+    → Hybrid: key docs in context, RAG for rest
+ELIF context > model_limit * 0.5:
+    → Pure RAG with reranking
+```
+
+### Key Insight: We're Mostly Fine
+Our current approach is actually reasonable:
+- **Hermes**: System prompt stuffed + selective skill loading + session search = hybrid approach. OK
+- **Memory**: FTS5 keyword search works but lacks semantic understanding. Upgrade candidate.
+- **Session recall**: Keyword search is limiting. Embedding-based would find semantically similar sessions.
+
+### Recommendations (Priority Order)
+1. **Keep current hybrid approach** — it's working well for 90% of tasks
+2. **Add semantic search to memory** — replace pure FTS5 with sqlite-vss or similar for the fact_store
+3. **Don't stuff sessions** — continue using selective retrieval for session history (saves cost)
+4. **Add context budget tracking** — log how many tokens each context injection uses
+
+### Conclusion
+We are NOT over-retrieving in most cases. The main improvement opportunity is upgrading memory from keyword search to semantic search, not changing the overall RAG vs stuffing strategy.
