/**
 * adapters/claude-code — Claude Code platform adapter.
 *
 * Implements HookAdapter for Claude Code's JSON stdin/stdout hook paradigm.
 *
 * Claude Code hook specifics:
 *   - I/O: JSON on stdin, JSON on stdout
 *   - Arg modification: `updatedInput` field in response
 *   - Blocking: `permissionDecision: "deny"` in response
 *   - PostToolUse output: `updatedMCPToolOutput` field
 *   - PreCompact: stdout on exit 0
 *   - Session ID: transcript_path UUID > session_id > CLAUDE_SESSION_ID > ppid
 *   - Config: ~/.claude/settings.json
 *   - Session dir: ~/.claude/context-mode/sessions/
