Summary

This updates repository badges to reflect current core/docs package versions and adds PR-visible framework
coverage reporting driven by test runs. CI coverage enforcement is now pytest-based with an 80% floor.

• Badge updates
  • Added core package version badge (0.2.2)
  • Added docs package version badge (0.2.1)
• Pytest standardization
  • Configured pytest in packages/core/pyproject.toml
  • Switched core test/coverage scripts from unittest to pytest + pytest-cov
  • Added root-level test script in package.json
• Coverage + CI behavior
  • Coverage workflow now runs pytest coverage with --cov-fail-under=80
  • Added PR coverage comment reporting
  • Scoped CI test execution to framework code/tests changes only

run: python -m pytest --cov=quickli --cov-report=term-missing --cov-report=xml --cov-fail-under=80

Why

The repo needed badges that reflect actual package versions and framework coverage that is collected from test
execution and surfaced during pull requests. The workflows now enforce coverage expectations and report
coverage deltas in PRs while avoiding unnecessary test runs when framework code/tests are unchanged.

Validation

Scope

• This pull request is focused on one feature or fix.
• Tests were added or updated for functional changes.
• Assumptions, risks, or follow-up work are described below.

Risks or follow-up

• README version badges are static and must be bumped with releases.
• CI test gating intentionally keys off packages/core/src/** and packages/core/tests/**; changes outside
  those paths will not trigger the test matrix.

• Fixes Readme badges #51
