feat: auto-detect claude binary to prevent ENOENT in launchd (v1.8.0)

The proxy previously defaulted to bare "claude" command which fails in
macOS LaunchAgent where PATH is minimal. Now resolves the binary at
startup via: CLAUDE_BIN env → well-known paths → which fallback.
Fails fast with clear error if binary cannot be found.

Also enhances /health to report claudeBinary and claudeBinaryOk status.
