chore(esign): 2.4.0 [skip ci]

### What's New

- **Tab character handling in text insertion** — Tab characters now convert to tab nodes during text insertion, with intelligent fallback to preserve raw tabs when parent nodes restrict tab node insertion.

### Fixes

- **Cursor placement in tracked changes** — Clicking directly on tracked-change text now places the cursor at the exact clicked position instead of activating the tracked change thread.
- **Config typings** — Refactored TypeScript configuration definitions for improved type clarity and maintainability.
