Symlink node_modules and husky in worktrees for JS tooling (#8422)

Worktrees don't have node_modules or .husky/_/husky.sh, breaking
pre-commit hooks (prettier, eslint) and JS tests. Fix by symlinking
both from the main repo after worktree creation.

Also add .husky/_ to .gitignore so the symlink doesn't show as
untracked, and update worktree paths to use ./worktrees/.
