chore(actions): add "Dependabot CI" workflow for automatic dependency merging

[panz3r]

Motivation

Improve maintainability and long-term support by auto-merging Dependanbot PRs

Description of Changes

This pull request introduces a new GitHub Actions workflow to automate the merging of Dependabot pull requests. The workflow is designed to run on pull requests and uses a third-party action to handle the merging process.

Automation and CI improvements:

• Added .github/workflows/dependabot-ci.yml to automatically squash-merge Dependabot pull requests using the fastify/github-action-merge-dependabot action.

How to Test

1. CI Checks: Verify that all automated tests (Vitest) and build steps pass successfully on this PR.
2. Local Verification (Optional):
   • Run pnpm install (or equivalent).
   • Run the development server (pnpm dev or equivalent) for the library or examples to ensure Vite starts correctly.
   • Run a build (pnpm build or equivalent) to ensure it completes successfully.
