fix: support Python 3.10

[vku2018]

Summary

Lowers the Python package minimum from 3.12 to 3.10 and adds the new minimum to CI.

This also fixes the one source syntax issue that Python 3.10 rejects: a nested f-string expression in cli.py that used an escaped quote. The output text is unchanged, but the expression is now built before the outer f-string.

Fixes #7.

Changes

• Set requires-python = ">=3.10".
• Add Python 3.10 and 3.11 classifiers.
• Add 3.10 and 3.11 to the CI matrix while keeping 3.12, 3.13, and 3.14.
• Document Python 3.10+ for the pip/pipx install path in English and Spanish READMEs.
• Make _print_claude_summary parse under Python 3.10.

Validation

• Parsed src, tests, and packaging with ast.parse(..., feature_version=(3, 10)).
• python -m compileall -q src tests packaging
• pytest -q tests/test_init.py::test_init_from_claude_md_creates_derived_rules tests/test_init.py::test_rules_from_claude_md_maps_signals_by_language tests/test_init.py::test_init_from_claude_md_composes_with_baseline tests/test_mcp.py::test_propose_rules_from_claude_md
• becwright check --all (blocking rules passed; existing warning-only comment findings remain warnings)
• git diff --check

I also ran the full local suite with Python 3.11 on Windows:

pytest -q --cov=src/becwright --cov-report=term-missing --cov-fail-under=80

Result: 275 passed, 13 failed. The failures appear to be existing Windows/POSIX-shell assumptions in tests and check commands, for example PYTHONPATH=..., true, and sleep being interpreted by cmd.exe. Coverage still reached 93.22%.

Summary by CodeRabbit

• New Features

  • Expanded Python compatibility to include Python 3.10 and 3.11.

📝 Walkthrough

Walkthrough

This PR lowers the minimum supported Python version to 3.10 by updating pyproject.toml's requires-python and classifiers, expanding the CI test matrix, updating README installation instructions, and includes a minor unrelated refactor in cli.py's summary printing.

Changes

Python 3.10 Minimum Version Support

Layer / File(s)	Summary
Packaging metadata and CI matrix update pyproject.toml, .github/workflows/ci.yml	requires-python lowered to >=3.10, header comment and Trove classifiers updated to reflect 3.10/3.11 support, and CI test matrix expanded to include Python 3.10 and 3.11.
README installation guidance update README.md, README.es.md	Instructions for installing via pipx on unsupported platforms now specify Python 3.10 or newer as the requirement.

Unrelated Refactor

Layer / File(s)	Summary
Claude summary formatting refactor src/becwright/cli.py	_print_claude_summary computes the matched-trigger label into a local variable before printing, replacing inline f-string formatting.

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Linked Issues check	❓ Inconclusive	The PR satisfies the version, CI, docs, and syntax-fix objectives, but full Python 3.10 test-suite success isn't shown.	Add evidence of a full test suite run on Python 3.10, or a CI job proving the new minimum passes end to end.

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title clearly summarizes the main change of lowering Python support to 3.10.
Description check	✅ Passed	The description covers the change, rationale, validation, and issue reference, even if the template headings differ.
Out of Scope Changes check	✅ Passed	The cli.py refactor is directly tied to the Python 3.10 syntax fix, and no unrelated changes are apparent.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
