Fix NLP package resolution in tests

[callumalpass]

Summary

• Bump tasknotes-nlp-core to 0.1.1, which publishes both ESM and CommonJS package exports
• Remove the Jest mapper that forced tests to resolve tasknotes-nlp-core from a local sibling checkout
• Add an unreleased note for the CI dependency-resolution fix

Test plan

• npm test -- tests/unit/services/NaturalLanguageParser.test.ts tests/unit/settings/TabButtons.css-classes.test.ts
• npm run typecheck
• git diff --check
• npm run test:ci -- --runInBand --silent
• OBSIDIAN_PLUGIN_PATH=/home/calluma/testvault/test/.obsidian/plugins/tasknotes npm run build:test
• obsidian plugin:reload id=tasknotes vault=test

Obsidian dev errors only showed the existing advanced-canvas errors, not TaskNotes errors.
