Error messages in coverage_utils.py hardcoded "Jest" even when the
test framework was Vitest. This caused confusion in logs when Vitest
tests failed (e.g., "Jest coverage file not found" when using Vitest).
The JestCoverageUtils class is used for both Jest and Vitest since
they share the same Istanbul/v8 coverage format. Error messages
should be framework-agnostic.
Changes:
- "Jest coverage file not found" → "JavaScript coverage file not found"
- "Failed to parse Jest coverage file" → "Failed to parse JavaScript coverage file"
- "No coverage data found for X in Jest coverage" → "No coverage data found for X in JavaScript coverage"
- "Function X not found in Jest fnMap" → "Function X not found in JavaScript fnMap"
