Summary

Consolidate grammaticalWords and ignoreList configuration from IPA-126 and IPA-117 rulesets into a shared utility file to eliminate duplication and maintain a single source of truth.

Proposed changes

• Create new utility file /tools/spectral/ipa/rulesets/functions/utils/grammaticalWordsAndIgnoreList.js with 4 exported constants
• Update IPA126TagNamesShouldUseTitleCase.js to import from shared utility instead of receiving parameters from YAML
• Update IPA117OperationSummaryFormat.js to import from shared utility instead of receiving parameters from YAML
• Remove hardcoded ignoreList and grammaticalWords from IPA-126.yaml and IPA-117.yaml for cleanup

Further comments

This refactoring reduces code duplication and improves maintainability by:

1. Keeping both IPA-126 and IPA-117 lists separate (they have different scopes - IPA-126 validates tag names, IPA-117 validates operation summaries)
2. Centralizing configuration management in one file
3. Making future updates easier - only need to update one file
4. All 696 tests pass with no regressions
5. npm run ipa-validation confirms no errors with the new validation rules
