/**
 * Bug #2557: Gemini CLI local hook commands must NOT use $CLAUDE_PROJECT_DIR.
 *
 * $CLAUDE_PROJECT_DIR is a Claude Code-specific env variable. Gemini CLI does
 * not set it. On Windows, Gemini's own variable-substitution + path-join logic
 * produced a doubled path like `D:\Projects\GSD\'D:\Projects\GSD'`, causing
 * every local project hook to fail at SessionStart.
 *
 * Fix: localPrefix is now runtime-conditional. Gemini/Antigravity use bare
 * dirName (relative path) since they always run project hooks with the project
 * dir as cwd. Claude Code and others still use "$CLAUDE_PROJECT_DIR"/ (#1906).
