/**
 * Regression test for #621: plan-phase gap-analysis must route through gsd_run
 *
 * Prior to the fix, line 1631 of plan-phase.md hardcoded:
 *   node "$HOME/.claude/gsd-core/bin/gsd-tools.cjs" gap-analysis ...
 * twice on the same line, breaking non-default install layouts.
 *
 * After the fix, both invocations route through gsd_run (the launcher defined
 * at line ~34 of the same file that resolves gsd-tools.cjs against
 * RUNTIME_DIR / git-toplevel / PATH / $HOME in order).
