/**
 * 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.
