Implements structured JSON diagnostic output for node state export with full
schema documentation. This feature provides machine-readable diagnostics for
automated analysis, monitoring, and AI/MCP integration.
Key changes:
- Add `zerotier-cli diagnostic` command for JSON node state export
- Add `zerotier-cli dump -j` as alias for JSON output
- Add `zerotier-cli diagnostic --schema` to print JSON schema
- Implement platform-specific interface collection (Linux, BSD, macOS, Windows)
- Create modular diagnostic/ directory with isolated try/catch error handling
- Add comprehensive JSON schema (diagnostic_schema.json) for validation
- Include build-time schema embedding for offline access
- Add Python and Rust scripts for schema embedding during build
- Update build systems to compile new diagnostic modules
The diagnostic output includes:
- Node configuration and identity
- Network memberships and settings
- Interface states and IP addresses
- Peer connections and statistics
- Moon orbits
- Controller networks (if applicable)
All diagnostic collection is wrapped in try/catch blocks to ensure partial
failures don't prevent overall output generation.

Unaligned access caused SIGBUS errors on ARMv6 and ARMv7 targets under FreeBSD.
This was also the cause of the repeating TAP devices. Each time the SIGBUS happened, the service would auto-restart itself, create a new TAP device, and then crash again.
The particular place causing the SIGBUS was:
