Feature: Add PR-dependency check

[DigiLive]

Feature Pull Request

Feature Summary

Add a GitHub Actions workflow to run dependency checks and report dependency issues in CI. Provides automated verification of third-party packages to help detect outdated or vulnerable dependencies early in the development process.

---

Motivation and Context

This workflow adds an automatic PR Dependency Check using the gregsdennis/dependencies-action.

The purpose is to enforce the correct merging order for Pull Requests (PRs). If a new PR is dependent on a change in another open PR or Issue, this check will fail until the dependency is successfully merged or closed.

---

Instructions

If your new PR must wait for another Issue or PR to be completed, include a dependency phrase in its description.

Key Phrase	Format	Example	Result
Depends on	Issue or PR Number	Depends on #42	PR is blocked until Issue/PR 42 is closed/merged.
Blocked by	Full Link	Blocked by [Refactor](https://github.com/org/repo/pull/101)	PR is blocked until the linked PR 101 is closed/merged.
Depends on	Partial Link	Depends on another-repo/project#5	Works for dependencies in a different repository.
Multiple Dependencies	List format	Depends on #5, #6, and #7	Requires all three to be closed/merged.
