Pull request overview
Updates the Part 5c course material to clarify a Vitest 4 behavior change where the coverage report only shows files touched by tests unless coverage is configured to include additional source files.
Changes:
- Adds a note explaining Vitest 4 default coverage reporting behavior.
- Adds an example configuration using test.coverage.include in vite.config.js to include uncovered source files in the report.

Vitest 4 only includes files covered by tests in the coverage report by
default, so the output can differ from the example shown in the course.
This adds a short note showing how to configure
coverage.includeinvite.config.jsso uncovered source files are also included in the report.
