Abstract base class for tunnel services (Cloudflare, Pinggy, ngrok). Defines a consistent lifecycle with start/stop/status/restart methods, subprocess spawning with stdio capture, and event emission. Isolates the tunnel-specific logic behind hooks, making it straightforward to add new tunnel providers without duplicating process management code.

Standalone error deduplication utility that throttles repeated log messages by error key within a configurable TTL. Supports summary intervals, cache cleanup, and custom log functions. Imports no internal modules, making it directly portable to any Node.js project needing to prevent log spam.

A Swift enum representing arbitrary JSON values (string, number, bool, null, array, object). Provides safe decoding/encoding with Codable, subscript access for nested dictionaries, and pretty-printing. Has no dependency on internal VibeTunnel types, making it a drop-in JSON representation for any Swift project.

Defines the WebSocket v3 binary framing protocol for terminal I/O. Includes magic number validation, version checking, message type enum (stdout, resize, event, etc.), and serialization/deserialization helpers. Self-contained and could be extracted as a shared library for any real-time terminal streaming application.

Implements a length-prefixed binary message protocol for Unix socket IPC between the Node.js server and the macOS app. Features message parser/builder with magic number, version, sequence ID, and type-value payload. Robust against partial reads and supports streaming. Reusable for any IPC requiring reliable framing.
