fix: added husky check and lock-file update

[cs-raj]

PR Description

Summary

Improves repo setup for contributors and CI: fixes Husky 9 pre-commit hook wiring, adds automatic hook installation on clone/install, upgrades jsdom with a matching Node engine, and keeps the repo clean by ignoring Husky’s internal directory.

Changes

Husky 9 & pre-commit hook

• Hook file name: Renamed .husky/.pre-commit → .husky/pre-commit so Husky 9 correctly discovers and runs the hook (Husky 9 expects hook names without a leading dot).
• Auto-install on clone: Added a prepare script that runs npx husky and chmod +x .husky/pre-commit, so after git clone + npm install, Git hooks are set up and the pre-commit hook runs on commit.
• Ignore Husky internal folder: Added .husky/_ to .gitignore. Husky 9 creates this directory when husky runs; it is not meant to be committed and will no longer show up in git status.

The pre-commit hook continues to run Talisman (secret scan) and Snyk (vulnerability scan); both must pass before a commit is allowed. Use SKIP_HOOK=1 to bypass when needed.

jsdom upgrade (v20 → v23)

• Dependency: Bumped jsdom from ^20.x to ^23.0.0.
• Compatibility: Existing usage (new JSDOM(html), dom.window.document.querySelector('body'), and passing the body node to collapse-whitespace and htmlToJson) relies only on stable DOM APIs and is compatible with jsdom 23.
• Node engine: Updated engines.node from >=14.0.0 to >=18.0.0 to align with jsdom 23’s requirement (Node 18+).

---

Testing

• npm install in a fresh clone runs prepare and sets up .husky/_ and executable .husky/pre-commit.
• git commit triggers the pre-commit hook (Talisman + Snyk) when Talisman and Snyk are installed.
• Existing tests pass with jsdom 23 and Node 18+.
• No .husky/_ or other Husky internals are committed; only .husky/pre-commit is tracked.

---

Notes for reviewers

• Contributors need Talisman and Snyk installed locally for the pre-commit hook to succeed; the hook prints clear errors if either is missing.
• Node 14/16 are no longer supported due to the jsdom 23 + engines.node bump; consider documenting this in the README if not already.
