Fixes #1429.

Select compact decimal plural forms using the rounded displayed value rather than the unrounded scaled value. Normalize optional fractional zeros before plural selection, since they are not displayed. For example, Russian 1100 now renders as 1 тысяча instead of 1 тысячи, and Polish 1900 renders as 2 tysiące instead of 2 tysiąca.

Add 11 regression cases covering positive and negative values, retained fractions, trimmed zeros, and five locales. Update the existing Italian 1234 expectation from 1 mila to mille, matching the rounded-value plural rule and Node's Intl formatter. The separate exact-1 pattern selection is unchanged.

Validation: CLDR 48.2 imported using the repository script; Python 3.12.15 on macOS; full suite: 7856 passed, 8 skipped, 2 xfailed. Ruff and git diff --check pass. The new regression tests fail on the original implementation.

Developed and tested with Codex assistance.

Let's also use the rounded value here:

Suggested change

	if scaled == 1 and "1" in compact_format:
	if rounded == 1 and "1" in compact_format:

and then change the tests accordingly and add

    ('fr', 1234, 0, 'mille'),
    ('fr', -1234, 0, '-1 millier'),

to the tests (this ought to match what Node ICU does).
