Restructure: reference/ and system/technical/ directories

- Moved technical docs from subconscious/ to reference/
- Created system/technical/ for always-loaded summaries
- Updated compass.md with new structure and update warnings
- system/technical/infrastructure.md — always-loaded summary
- system/technical/sam.md — always-loaded summary
- reference/ holds full docs

CRITICAL: system/technical/ files must be kept updated

+# Synu & Synthetic API
+
+## The Shell Context
+
+**Laptop (Casey):** zsh — synu as zsh plugin
+**Fedora .19 VM (Ani):** fish — synu as fish function
+
+I invoke explicitly: `fish -c 'synu ...'` on .19 VM
+
+## Quick Check
+
+```bash
+curl https://api.synthetic.new/openai/v1/models \
+  -H "Authorization: Bearer ${SYNTHETIC_API_KEY}"
+```
+
+## Synu Usage
+
+```bash
+# Show quota (green/yellow/red bars)
+synu
+
+# Run agent with prompt
+synu <agent> -p "prompt here"
+
+# Interactive mode with flag selection
+synu i <agent>
+```
