/**
 * adapters/vscode-copilot — VS Code Copilot platform adapter.
 *
 * Implements HookAdapter for VS Code Copilot's JSON stdin/stdout hook paradigm.
 *
 * VS Code Copilot hook specifics:
 *   - I/O: JSON on stdin, JSON on stdout (same paradigm as Claude Code)
 *   - Hook names: PreToolUse, PostToolUse, PreCompact, SessionStart (PascalCase)
 *   - Additional hooks: Stop, SubagentStart, SubagentStop (unique to VS Code)
 *   - Arg modification: `updatedInput` in hookSpecificOutput wrapper (NOT flat)
 *   - Blocking: `permissionDecision: "deny"` (same as Claude Code)
 *   - Output modification: `additionalContext` in hookSpecificOutput,
 *     `decision: "block"` + reason
 *   - Tool input fields: tool_name, tool_input (snake_case, same as Claude Code)
 *   - But tool input PROPERTY names are camelCase (filePath not file_path)
 *   - Session ID: sessionId (camelCase, NOT session_id)
 *   - MCP tool prefix: f1e_ (not mcp__server__tool)
 *   - CRITICAL: matchers are parsed but IGNORED (all hooks fire on all tools)
 *   - Config: .github/hooks/*.json (primary), also reads .claude/settings.json
 *   - Env detection: VSCODE_PID, TERM_PROGRAM=vscode
 *   - Session dir: ~/.vscode/context-mode/sessions/ (fallback)
 *   - Preview status — API may change
