/**
 * Tests for hook timeout and exit code constants
 *
 * Mock Justification (~12% mock code):
 * - process.platform: Only mocked to test cross-platform timeout multiplier
 *   logic - ensures Windows users get appropriate longer timeouts
 *
 * Value: Prevents regressions in timeout values that could cause
 * hook failures on slow systems or Windows
