Fixes #2428. Thanks to @starise for the reproduction and root-cause analysis.

The implementation lives in tasknotes-nlp-core, not the plugin. Source fixes merged as callumalpass/tasknotes-nlp-core#6 and callumalpass/tasknotes-nlp-core#7 after green CI. Pin the final immutable merge commit c148eed995f8de0f9fa7a8bf4d7177ddb69c145a over HTTPS (prepare builds ESM/CJS on install); no npm publication, tag, version bump or plugin release.

• Adds entro le and complete masculine/feminine scheduled triggers. Specificity-based Italian precedence protects both scheduled phrases and existing entro il/per il due phrases.
• Unicode-aware recurrence boundaries with u preserve accented weekday endings and prevent matches inside longer Unicode words or hyphenated titles.
• 41 new core tests: all reported rows and working controls; seven weekdays; punctuation, ordinal/plural forms; Unicode negative cases; weekday spellings across all 12 languages; due controls and mixed due/scheduled input in either order. Core suite: 89 passed.
• 19 plugin adapter regressions using real date libraries, including all reported rows and working controls. NLP suite: 237 passed, 21 pre-existing skips.
• Updates the existing Italian locale smoke expectation for relative-day support already present in the newer core.

Local lint, typecheck, production build, bundle-size budget, 77 integration tests and all 62 i18n-source tests pass. Local full coverage run exceeded the 120s command budget without reported failures. Hosted full plugin CI pending.
