+/**
+ * Regression tests for bugs #1852 and #1862
+ *
+ * The package.json "files" field listed "hooks/dist" but not "hooks" directly.
+ * The three .sh hook files live in hooks/ (not hooks/dist/), so they were
+ * excluded from the npm tarball. Any fresh install from the registry would
+ * produce broken shell hooks (SessionStart / PostToolUse errors).
+ *
+ * Fix: change "hooks/dist" to "hooks" in package.json so that the entire
+ * hooks/ directory (both .js dist files and .sh source files) is included.
