Release v0.6.3

Patch release adding optional auth token protection for self-hosted servers, resolving 100% idle CPU dial spin, and improving test coverage.

What's Changed

• Auth Token Security (#63, #116): Added optional --token flag and EXPOSE_SERVER_TOKEN environment variable to protect self-hosted relay servers against unauthorized tunnel registrations. Verified using timing-attack safe comparison (crypto/subtle.ConstantTimeCompare).
• Fixed 100% CPU Dial Spin (#55, #113): Replaced unbounded dial loop with a bounded worker pool (clamped to max 30) with exponential backoff and dynamic server-advertised max_connections.
• Test Coverage & Reliability (#110, #116): Added unit test suites for CLI commands (config, init, root, server, tunnel), tunnel service lifecycle, and dev version fallback.
• Documentation: Updated self-hosted security docs, installation pinning, and Docker Compose configurations.
