/**
 * adapters/claude-code-base — Shared base for Claude Code wire-protocol adapters.
 *
 * Claude Code and Qwen Code use the identical JSON stdin/stdout hook protocol:
 *   - Input fields: tool_name, tool_input, tool_output, is_error, session_id,
 *     transcript_path, source
 *   - Blocking: `permissionDecision: "deny"` in response
 *   - Arg modification: `updatedInput` field in response
 *   - Output modification: `updatedMCPToolOutput` field in response
 *   - Context injection: `additionalContext` at response root (not wrapped)
 *   - PreCompact/SessionStart: stdout on exit 0
 *
 * This base class implements the 8 shared parse/format methods.
 * Subclasses provide platform-specific config (env vars, settings path,
 * session ID priority, hook config, diagnostics, upgrade).
