1.4.1 release

[serhii73]

Release notes and version bump for dateparser 1.4.1, following the same two-step approach used for 1.4.0 (#1319 + the subsequent bump commit):

1. 1.4.1 release notes — add the 1.4.1 section to HISTORY.rst, summarizing every PR merged since v1.4.0.
2. Bump version: 1.4.0 → 1.4.1 — produced by bump-my-version bump patch, updating pyproject.toml, dateparser/__init__.py, and stamping the HISTORY.rst release date. SECURITY.md is unchanged because it tracks only major.minor (still 1.4.x).

Changelog

Breaking changes:

• Remove fastText language detection support; the fasttext extra is dropped and detect_languages() now raises ImportError. Migrate to the langdetect extra, which also unblocks numpy 2.x compatibility (Remove fastText support and enable numpy 2.x compatibility #1315)

Security fixes:

• Make digit quantifiers possessive in the relative-date regexes to prevent quadratic backtracking (ReDoS) on long digit runs (make relative-date regex digit quantifiers possessive #1335)

New features:

• Add the USE_GIVEN_LANGUAGE_ORDER setting to try languages and locales in the order given rather than by frequency (Locale order support #789)

Fixes:

• Preserve explicit signs on individual components when parsing relative dates that combine decades with years (fix: Preserve explicit signs for years when combined with decades #1330)
• Fall back to other provided languages in search_dates when the detected language yields no dates (Fix search_dates language fallback #1331)
• Parse relative date expressions with spaces between the sign and number, e.g. now - 2 hours (Handle spaces around operators #1327)
• Use the parser-relative now for the current month when filling in incomplete dates (Document region usage and stabilize current-month parsing #1332)
• Fix Norwegian Bokmål (nb) parsing of relative date expressions (fix(nb): improve Norwegian Bokmål date parsing #1334)
• Parse abbreviated English month expressions such as 1mon ago (fix: Parse 1mon ago #1329)
• Preserve surrounding whitespace when removing skip tokens during translation (fix: preserve whitespace when removing translation tokens (fix #1302) #1324)

Improvements:

• Move project metadata and build configuration to pyproject.toml (Move project metadata and configuration to 'pyproject.toml' #1311)
• Add alternative Korean date expressions (Add Korean alternative date expressions #1289)
• Expand Czech date translations (Better cs translation #1325)
• Replace internal OrderedDict usage with the built-in dict (Replace internal OrderedDict usage with dict #1328)

After merge

The v1.4.1 git tag is intentionally not included in this branch (a tag on a pre-merge branch would point at the wrong commit). After merging, tag the merge commit on master:

git tag v1.4.1 && git push origin v1.4.1

Internal-only changes (#1333 data-generation script cleanup, #1320 Read the Docs CI bump) were deliberately omitted from the changelog.
