This PR is titled as a CI-only Codecov action upgrade, but it also deletes licenses/rust/LICENSE-{MIT,APACHE}. If those files were kept for third-party license attribution/compliance, they should not be removed; otherwise please update the PR title/description (or split into a separate PR) to reflect the licensing change explicitly.

[Copilot]

The "Upload test results" step switches from codecov/test-results-action@v1 to codecov/codecov-action@v5 and introduces report_type: test_results. Since this changes the upload mechanism, please confirm this is the supported way to upload JUnit results with v5 (and that the inputs are correct). If not, keep using the dedicated codecov/test-results-action for test results while upgrading only the coverage upload step.
