Decide and modernize @appdmg/tn1150 for Node.js 24

[jozefizso]

Item 3: Modernize @appdmg/tn1150

Suggested repository: new or existing appdmg-owned repository

Created issue: #5

Project item: added to appdmg

Goal

Determine whether TN1150/HFS Unicode behavior still needs a package, then
publish or replace it with fixture-backed confidence.

Requirements

• Capture existing Unicode normalization behavior with tests.
• Compare behavior against modern Node.js string normalization.
• Preserve compatibility if appdmg still needs the package.
• Use CommonJS and AVA.
• Set engines.node to >=24.
• Publish under @appdmg/tn1150 only if a package remains necessary.

Acceptance Criteria

• Decision is documented: keep package, replace with built-in API, or defer.
• Tests cover representative HFS/TN1150 normalization cases.
• If kept, package metadata is ready for a 1.0.0 scoped release.

Created the new package repository and opened PR #1 for the Node.js 24 modernization: appdmg/tn1150#1

Decision: keep the package as @appdmg/tn1150 because compare() carries the TN1150/HFS Plus ordering table, but remove unorm and use Node's built-in text.normalize('NFD') for normalization.

Current local verification on Node.js 24.14.0:

• npm ci
• npm test
• npm audit --audit-level=moderate
• npm ls --omit=dev --all
• npm pack --dry-run
• node --check index.js
• node --check test.js

Updated appdmg/tn1150 PR #1 to include a Node.js 24 build workflow using actions/checkout@v6 and actions/setup-node@v6. Refreshed PR and push workflow runs are green.
