ci: tighten Codecov coverage gates

[MapleEve]

Summary

• set Codecov project coverage gate to 90%
• set Codecov patch coverage gate to 80%
• set threshold tolerance to 0% for both gates

Validation

• codecov.yml parsed locally
• git diff --check passed
• public release scan passed

Note

If current project coverage is below 90%, the Codecov project check should fail by design until coverage is raised.

Pull request overview

This PR tightens Codecov’s coverage enforcement by raising the required coverage targets and removing any tolerance/threshold slack, increasing the strictness of CI coverage checks.

Changes:

• Increase project coverage target from 70% to 90%.
• Increase patch coverage target from 60% to 80%.
• Set threshold: 0% for both project and patch statuses (no allowed drop below target).
