Summary

• Add Brazilian Portuguese number, currency, time, and common unit normalization.
• Register language code p and add focused regression cases.
• Leave invalid times and long identifier-like digit runs unchanged.

Closes #392

Validation

• py_compile passed for the implementation and test module.
• Direct normalization smoke checks passed for integers, currencies, times, units, and long digit runs.
• The pytest suite could not be run here: pytest and ruff were unavailable, and installing test dependencies failed because the local Python/SDK build environment could not compile pydantic-core.

Hey @Udbhav-regadamilli, thanks for this. A few things before it can go in:

• CI is failing on the two unit cases. unit_normalization is off by default (same as English), so those cases need NormalizationOptions(unit_normalization=True). Worth keeping one default case showing km left alone too
• Needs a rebase, or I can resolve on this end; just the CHANGELOG section.
• num2words only comes in through misaki right now, can you add it to the deps in pyproject.toml directly
• We'd want to add a few Portuguese floods to test_normalizer_redos.py (digit runs, 1.000 runs, R$1, runs etc) through get_normalizer("p"), since these regexes run on request text
