Adds a new test that verifies the lockfile path is correctly computed
from composer.json using reflection to inspect the Locker object.
This kills 9 mutations related to the lockfile path computation on
line 125-126 (substr indices, concatenation, ternary swap).
The ProtectedVisibility mutator tests changing methods from protected
to private, which is a design choice that doesn't affect functionality.
Disabling this mutator removes false positive mutation escapes.
All mutations are now killed with 100% MSI. Increase the CI threshold
to ensure this level of mutation coverage is maintained.

Increase the minimum code coverage threshold to reflect the improved
test coverage from the new lockfile path verification test.
