feat: add picoclaw doctor diagnostic command

Added comprehensive diagnostic tool for checking PicoClaw setup:
- Configuration file validation
- Workspace accessibility and permissions
- LLM provider configuration and connectivity testing
- Tool status checking (Brave, DuckDuckGo, Firecrawl, SerpAPI)
- Chat channel configuration

Features:
- Visual status indicators (✅ ⚠️ ❌)
- Network connectivity tests for configured providers
- Detailed error messages with fix suggestions
- Exit codes: 0 for success, 1 for errors

Docker improvements:
- Added picoclaw-doctor service to docker-compose.yml
- Added environment variable support for API keys
- Updated .env.example with all provider options
- Added test script (test-doctor.sh)

New files:
- pkg/doctor/doctor.go: Main diagnostic logic
- pkg/doctor/doctor_test.go: Unit tests
- pkg/doctor/README.md: Documentation
- test-doctor.sh: Quick test script

Modified:
- cmd/picoclaw/main.go: Added doctor command
- Dockerfile: Added environment variables
- docker-compose.yml: Added doctor service
- .env.example: Added all provider and tool options

+# PicoClaw Doctor
+
+A diagnostic tool for checking PicoClaw configuration and connectivity.
+
+## Usage
+
+```bash
+picoclaw doctor
+```
+
+## What it checks
+
+1. **Configuration File** - Verifies config exists and is valid JSON
+2. **Workspace** - Checks workspace directory exists and is writable
+3. **LLM Providers** - Lists configured providers and their API keys
+4. **Provider Connectivity** - Tests network connectivity to configured providers
+5. **Tools** - Lists enabled tools (Brave, DuckDuckGo, Firecrawl, SerpAPI)
+6. **Channels** - Lists enabled chat channels
+
+## Docker Usage
+
+```bash
+# Run doctor with Gemini API key
+docker compose run --rm picoclaw-doctor
+
+# Or set your API key in environment
+export GEMINI_API_KEY=your-key-here
+docker compose run --rm picoclaw-doctor
+```
+
+## Exit Codes
+
+- `0` - All checks passed
+- `1` - One or more errors found
+
+## Example Output
+
+```
+🏥 PicoClaw Doctor
+==================
+
+✅ Configuration File
+   Configuration loaded successfully
+   Path: /root/.picoclaw/config.json
+
+✅ Workspace
+   Workspace is accessible and writable
+   Path: /root/.picoclaw/workspace
+
+✅ LLM Providers
+   1 provider(s) configured
+   ✓ Gemini
+
+✅ Provider Connectivity
+   All 1 tested providers reachable
+   ✓ Gemini: Reachable
+
+⚠️ Tools
+   No tools enabled
+   At least DuckDuckGo search is recommended
+
+✅ Channels
+   No channels enabled (CLI mode only)
+
+----------
+✅ 5 passed  ⚠️ 1 warnings  ❌ 0 errors
+
+⚠️  PicoClaw should work, but consider addressing the warnings
