/**
 * Bug #2418: Found unreplaced .claude path reference(s) in Antigravity install
 *
 * The Antigravity path converter handles ~/.claude/ (with trailing slash) but
 * misses bare ~/.claude (without trailing slash), leaving unreplaced references
 * that cause the installer to warn about leaked paths.
 *
 * Files affected: agents/gsd-debugger.md (configDir = ~/.claude) and
 * gsd-core/workflows/update.md (comment with e.g. ~/.claude).
