Check the runtime threshold type before range membership so numerically equal floats cannot enter immutable BIP93 headers and fail later during symbol encoding. Security: strengthens the validated-artifact construction boundary without changing valid integer thresholds. Validation: focused public API and BIP93 tests; Ruff check and format; strict mypy.

What
Require
Header.thresholdto be a non-boolean integer before checking the BIP93range.
Why
Python numeric equality allowed
2.0through the range-membership check, leavinga float in an otherwise validated immutable header and failing later during
Bech32 symbol encoding. This adapts
Rob1Ham/python-codex32#11
onto the current target.
