fix: exclude patchloomCli.test.js from coverage

The patchloomCli tests depend on the patchloom binary being on PATH.
In CI on Ubuntu, the binary is not available so tests skip, causing
the test file's coverage to drop from 88% to 17% and failing the
80% threshold. Exclude this environment-dependent test file from
coverage measurement.

Also add --test-coverage-include to limit coverage to source files
only (not test files) for cleaner measurement.
