Release 0.3.0

[anyrobert]

Summary

Adds stream deduplication, a Windows cmd.exe length bypass, and centralized env handling. Includes tests and docs.

Changes

Stream deduplication

• Introduces createStreamParser() to replace parseCliStreamLine
• Tracks accumulated text and skips the final duplicate full message from the Cursor CLI
• Emits only deltas so clients see each chunk once

Windows cmd.exe length limit

• Adds CURSOR_AGENT_NODE and CURSOR_AGENT_SCRIPT to spawn Node directly
• Bypasses the ~8191-character limit when using long prompts
• Uses cmd.exe /d /s /c with quoted args for .cmd invocations when those env vars are not set

Centralized env module

• Adds src/lib/env.ts as the single source of truth for env handling
  loadEnvConfig(opts) supports aliases, defaults, path resolution, and --tailscale host fallback
• resolveAgentCommand(cmd, args, opts) encapsulates Windows spawn logic
• config.ts and cli.ts read from the env module instead of process.env
• --tailscale is passed as an option instead of mutating process.env

Other

• Tests: cli-stream-parser.test.ts, env.test.ts, process.test.ts; updated config.test.ts
• Fix: add logTrafficRequest, logTrafficResponse, logAgentError to the server test mock
• Docs: README updated for env vars, aliases, and Windows usage
• Version bump: 0.2.0 → 0.3.0
