chore(ci): remove dead Codecov upload steps + lock pins

[hyperpolymath]

Removed CI references to apps that are no longer installed on this account/org.

Why this is a fix, not a tidy-up

• Codecov was uninstalled as a GitHub App, but its action steps remain in workflows.
• The estate Actions allowlist already pruned codecov/codecov-action@* (standards/config/settings/actions-allowlist.json -> pruned_from_live_2026_09_02), so a workflow still calling it fails at job start instead of quietly no-op-ing.
• Snyk / Codacy / Mergify / ImgBot / CodeFactor are on the estate never-re-add list (standards spec §9, rulings R1/R4/R5).

Changes

• .github/workflows/ci.yml — applied
• .github/workflows/integration-tests.yml — applied

Notes

• actions.lock entries for the removed actions are deleted in this same commit (the same-PR regen rule in the CI/CD regularisation spec §6.4), so actions-lock-verify sees no drift.
• Removals are line-exact; no other line was reformatted and no comment was re-wrapped.
• Historical records (milestone logs, CHANGELOG, audit docs, specs) that describe the removal were deliberately left untouched.
• The gitar-approved label is intentionally frozen per docs/LABELS.adoc — it is not an active Gitar install, so it stays.

📝 Summary

Summary by CodeRabbit

• Chores
  • Updated CI reporting to reference locally generated coverage artifacts.
  • Removed automated coverage uploads from test workflows.
  • Removed the automated security scan from the CI workflow.
  • Integration tests continue to run without uploading coverage results.

Walkthrough

The CI workflows remove Codecov upload steps and the Snyk security scan. The coverage report output now points to lcov and cobertura artifacts.

Changes

CI workflow updates

Layer / File(s)	Summary
Coverage reporting changes .github/workflows/ci.yml, .github/workflows/integration-tests.yml	The test jobs no longer upload coverage results to Codecov. The coverage report output references the lcov and cobertura artifacts.
Security scan removal .github/workflows/ci.yml	The security job no longer runs the Snyk scan or supplies the SNYK_TOKEN secret.

123-123: 🔒 Security & Privacy | 🛡️ Analyzed with Security Review

The non-blocking npm audit step is not the repository’s only security control.

hypatia-scan.yml runs on pull requests, pushes, and a weekly schedule. Its pinned reusable workflow processes Dependabot, code-scanning, and secret-scanning alerts, and CodeQL analyses JavaScript/TypeScript. Dependabot also monitors npm dependencies weekly. The claim that removing Snyk leaves the documented security coverage unestablished is not supported.

Likely an incorrect or invalid review comment.

Upload the coverage artefacts before referring to them.

test-julia and test-typescript generate coverage data, but neither job uploads lcov.info or coverage/cobertura-coverage.xml. The existing upload steps are in build and cover only build outputs. As a result, the coverage-report message points to artefacts that users cannot access after the test jobs finish. Add actions/upload-artifact steps in the test jobs for the generated coverage files.
