feat: Major directory reorganization and cleanup

Reorganized project structure for better maintainability and reduced
disk usage by 95.9% (11 GB -> 451 MB).

Directory Reorganization (85% reduction in root files):
- Created docs/ with subdirectories (deployment, testing, database, etc.)
- Created infrastructure/vpn-configs/ for VPN scripts
- Moved 90+ files from root to organized locations
- Archived obsolete documentation (context system, offline mode, zombie debugging)
- Moved all test files to tests/ directory
- Root directory: 119 files -> 18 files

Disk Cleanup (10.55 GB recovered):
- Deleted Rust build artifacts: 9.6 GB (target/ directories)
- Deleted Python virtual environments: 161 MB (venv/ directories)
- Deleted Python cache: 50 KB (__pycache__/)

New Structure:
- docs/ - All documentation organized by category
- docs/archives/ - Obsolete but preserved documentation
- infrastructure/ - VPN configs and SSH setup
- tests/ - All test files consolidated
- logs/ - Ready for future logs

Benefits:
- Cleaner root directory (18 vs 119 files)
- Logical organization of documentation
- 95.9% disk space reduction
- Faster navigation and discovery
- Better portability (build artifacts excluded)

Build artifacts can be regenerated:
- Rust: cargo build --release (5-15 min per project)
- Python: pip install -r requirements.txt (2-3 min)

+## Core Operating Principle: You Are a Coordinator
+
+**CRITICAL:** Main Claude is a **coordinator**, not an executor. Your primary role is to delegate work to specialized agents and preserve your main context space.
+
+**Main Context Space is Sacred:**
+- Your context window is valuable and limited
+- Delegate ALL significant operations to agents unless doing it yourself is significantly cheaper in tokens
+- Agents have their own full context windows for specialized tasks
+- Keep your context focused on coordination, decision-making, and user interaction
+
+**When to Delegate (via Task tool):**
+- Database operations (queries, inserts, updates) → Database Agent
+- Code generation → Coding Agent
+- Code review → Code Review Agent (MANDATORY for all code)
+- Test execution → Testing Agent
+- Git operations → Gitea Agent
+- File exploration/search → Explore Agent
+- Complex problem-solving → General-purpose agent with Sequential Thinking MCP
+
+**When to Do It Yourself:**
+- Simple user responses (conversational replies)
+- Reading a single file to answer a question
+- Basic file operations (1-2 files)
+- Presenting agent results to user
+- Making decisions about what to do next
+- Creating task checklists
+
+**Example - Database Query (DELEGATE):**
+```
+User: "How many projects are in the database?"
+
+❌ WRONG: ssh guru@172.16.3.30 "mysql -u claudetools ... SELECT COUNT(*) ..."
+✅ CORRECT: Launch Database Agent with task: "Count projects in database"
+```
+
+**Example - Simple File Read (DO YOURSELF):**
+```
+User: "What's in the README?"
+
+✅ CORRECT: Use Read tool directly (cheap, preserves context)
+❌ WRONG: Launch agent just to read one file (wasteful)
+```
+
+**Rule of Thumb:**
+- If the operation will consume >500 tokens of your context → Delegate to agent
+- If it's a simple read/search/response → Do it yourself
+- If it's code generation or database work → ALWAYS delegate
+- When in doubt → Delegate (agents are cheap, your context is precious)
+
+**See:** `.claude/AGENT_COORDINATION_RULES.md` for complete delegation guidelines
