This commit adds a new documentation website built with MkDocs and the Material theme.
The website includes pages for:
- Trix & Sigil Chaining
- Hashing
- Checksums
- RSA
- Standalone Sigils
A GitHub Actions workflow is also included to automatically build and deploy the site to GitHub Pages when changes are merged into the main branch.
This commit adds a step to the GitHub Actions workflow to generate and upload a test coverage report. It also renames the `Verifyf` function in the `lthn` package to `Verify` to match the Core repository.
