Adds a coverage job to the CI workflow that runs the test suite under Devel::Cover and uploads results to Codecov. This provides visibility into which code paths are exercised by tests (baseline: ~55% coverage). Also adds cover_db/ to .gitignore to prevent accidental commits of local coverage data.

Prevents Devel::Cover output from being included in CPAN tarballs if someone runs `cover -test` before `make dist`. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Remove Devel::Cover::Report::Codecov — the codecov-action reads cover_db/ directly. The space-separated install string was also being parsed as a single module name by cpm. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

What
Adds a code coverage CI job that runs the test suite under Devel::Cover and uploads results to Codecov.
Why
Coverage visibility helps identify untested code paths and guides future test work. The current baseline is ~55% overall coverage (statement: 66%, branch: 49%, condition: 31%, subroutine: 80%).
