Description of Changes

Constructor-style calls such as ArrowFactory().get(2024, 6, 1) and arrow.get(year=2024, month=6, day=1) work at runtime but fail type checking because the corresponding overloads are missing. Add a constructor overload to each public entry point, covering positional and keyword date fields, optional time fields, timezone and fold. Existing overloads and runtime behavior are unchanged.

Add static regression checks to the existing mypy hook. Eleven supported calls fail before the change and pass after it; incomplete dates and string day values remain rejected. The fixture is explicitly enabled in the mypy configuration because other test modules skip type errors.

Validation on Windows with Python 3.12:

• Static regression fixture passes mypy; all 12 supported calls also execute successfully.
• Full suite: 1,901 passed, 1 skipped; 99.93% coverage.
• All pre-commit hooks and the warnings-as-errors Sphinx build pass.

No documentation update is needed: these constructor forms are already supported and documented. This change was developed with OpenAI Codex.
