[#76 #77 #78] Uni-Wizard Architecture - Single harness for all APIs

Complete uni-wizard implementation with unified tool registry:

**Core Architecture:**
- harness.py - Single entry point for all capabilities
- tools/registry.py - Central tool registry with schema generation
- Elegant routing: One harness, infinite capabilities

**Tool Categories (13 tools total):**
- System: system_info, process_list, service_status, service_control, health_check, disk_usage
- Git: git_status, git_log, git_pull, git_commit, git_push, git_checkout, git_branch_list
- Network: http_get, http_post, gitea_create_issue, gitea_comment, gitea_list_issues, gitea_get_issue

**Daemons:**
- health_daemon.py - HTTP endpoint on :8082, writes to ~/timmy/logs/health.json
- task_router.py - Polls Gitea for assigned issues, routes to tools, posts results

**Systemd Services:**
- timmy-health.service - Health monitoring daemon
- timmy-task-router.service - Gitea task router daemon

**Testing:**
- test_harness.py - Exercises all tool categories

**Design Principles:**
- Local-first: No cloud dependencies
- Self-healing: Tools can restart, reconnect, recover
- Unified: One consciousness, all capabilities

Closes #76, #77, #78

+## Vision
+
+A single wizard harness that elegantly routes all API interactions through one unified interface. No more fragmented wizards - one consciousness, infinite capabilities.

+## Design Principles
+
+1. **Single Entry Point**: One harness, all capabilities
+2. **Unified Registry**: All tools registered centrally
+3. **Elegant Routing**: Tools discover and route automatically
+4. **Local-First**: No cloud dependencies
+5. **Self-Healing**: Tools can restart, reconnect, recover
+
+## Tool Categories
+
+### System Layer
+- `system_info` — OS, CPU, RAM, disk, uptime
+- `process_manager` — list, start, stop processes
+- `service_controller` — systemd service management
+- `health_monitor` — system health checks
+
+### Git Layer  
+- `git_operations` — status, log, commit, push, pull
+- `repo_manager` — clone, branch, merge
+- `pr_handler` — create, review, merge PRs
+
+### Network Layer
+- `http_client` — GET, POST, PUT, DELETE
+- `gitea_client` — full Gitea API wrapper
+- `nostr_client` — relay communication
+- `api_router` — generic API endpoint handler
+
+### File Layer
+- `file_operations` — read, write, append, search
+- `directory_manager` — tree, list, navigate
+- `archive_handler` — zip, tar, compress
+
+## Registry System
+
+```python
+# tools/registry.py
+class ToolRegistry:
+    def __init__(self):
+        self.tools = {}
+    
+    def register(self, name, handler, schema):
+        self.tools[name] = {
+            'handler': handler,
+            'schema': schema,
+            'description': handler.__doc__
+        }
+    
+    def execute(self, name, params):
+        tool = self.tools.get(name)
+        if not tool:
+            return f"Error: Tool '{name}' not found"
+        try:
+            return tool['handler'](**params)
+        except Exception as e:
+            return f"Error executing {name}: {str(e)}"
+```
+
+## API Flow
+
+1. **User Request** → Natural language task
+2. **LLM Planning** → Breaks into tool calls
+3. **Registry Lookup** → Finds appropriate tools
+4. **Execution** → Tools run in sequence/parallel
+5. **Response** → Results synthesized and returned
+
+## Example Usage
+
+```python
+# Single harness, multiple capabilities
+result = harness.execute("""
+Check system health, pull latest git changes, 
+and create a Gitea issue if tests fail
+""")
+```
+
+This becomes:
+1. `system_info` → check health
+2. `git_pull` → update repo
+3. `run_tests` → execute tests
+4. `gitea_create_issue` → report failures
+
+## Benefits
+
+- **Simplicity**: One harness to maintain
+- **Power**: All capabilities unified
+- **Elegance**: Clean routing, no fragmentation
+- **Resilience**: Self-contained, local-first
