fix(hooks): remove deprecated husky shim and add package-manager fall…

Description

This PR fixes pre-commit hook reliability issues by removing deprecated Husky shim usage and adding package-manager fallback support.

The hook now works even when Yarn is not globally available, preventing commit failures such as command not found during pre-commit.

Why This Change

• Husky shim style used in hooks is deprecated and will fail in future Husky versions.
• Pre-commit previously depended on Yarn being present in PATH.
• Developers using npm or pnpm could not commit successfully.

What Changed

• Removed deprecated Husky shim invocation from pre-commit hook.
• Added package-manager fallback logic in pre-commit:
  • Yarn first
  • pnpm second
  • npm/npx fallback
• Replaced Yarn-only lint-staged audit command with a portable script approach.

Impact

• No runtime/backend behavior changes.
• Improves developer experience and onboarding.
• Reduces commit-time failures across different local setups.

Validation

• Pre-commit hook executes successfully without deprecated shim usage.
• Hook runs lint-staged without requiring global Yarn.
• Fallback path works when different package managers are used.
