Fix false PASSED on XHarness app crash (exit 83)

When XHarness crashes with exit code 83 (APP_LAUNCH_FAILURE), the
test runner outputs 'Passed: 0 / Failed: 0'. The parser was not
detecting this as an env error because:
1. The regex 'APP_LAUNCH_FAILURE|exit code:? 83' didn't match the
   actual format 'XHarness exit code: 83 (APP_LAUNCH_FAILURE)'
2. 'Passed: 0 / Failed: 0' fell through all checks to the generic
   'Could not parse' path, but in some flows was treated as PASSED

Fixes:
- Add 'XHarness exit code: 83' as explicit env error pattern
- Add 'Application test run crashed' as env error pattern
- Guard: 'Passed: 0 + Failed: 0' = env error (zero tests ran)
