When both decades and years are present (e.g. '-1 decade +2 years'), the code in get_kwargs() unconditionally overwrote explicit_signs['years'] with the decades sign value:

if 'decades' in explicit_signs:
    explicit_signs['years'] = explicit_signs['decades']

This destroyed the user-supplied +/- that was recorded for years during the PATTERN match loop, causing _parse_date() to mishandle the sign of the merged years value.

Fix: only propagate the decades sign to years when years did not carry its own explicit sign (explicit_signs.get('years') is False/absent).

Regression tests added for:

• '-1 decade' (only decades, negative)
• '-1 decade 2 years' (decades negative, years implicit)
• '-1 decade +2 years' (decades negative, years explicitly positive)
• '+2 years' (only years, explicitly positive future)
• '1 decade +2 years' (decades implicit, years explicitly positive)
• '+1 decade -2 years' (decades explicitly positive, years explicitly negative)

Fixes #1304

Pull request overview

Fixes a sign-handling bug in the freshness/relative-date parser where combining decades and years could overwrite an explicitly provided sign on years (e.g. -1 decade +2 years), leading to incorrect direction when computing the final relative delta.

Changes:

• Update FreshnessDateDataParser.get_kwargs() to only propagate the decades explicit-sign flag to years when years does not already have its own explicit sign.
• Add regression tests covering mixed-sign and explicit-sign combinations for decades+years (and standalone explicitly-signed years).

File	Description
dateparser/freshness_date_parser.py	Preserves an explicit +/- on years when merging decades into years, preventing incorrect sign inversion.
tests/test_freshness_date_parser.py	Adds regression coverage for the decades+years explicit-sign interaction, including mixed-sign cases.
