📝 Walkthrough

Walkthrough

This pull request expands the Miren platform glossary documentation with comprehensive terminology coverage. The front matter description is broadened to explicitly mention routes and addons. The glossary is enlarged with foundational platform concepts including Addon, app.toml, Build, Cold Start, Concurrency, and others. Additional terminology entries cover advanced networking, deployment, and traffic management concepts such as Node Port, OIDC Binding, Route Protection, Sandbox Pool, Scale to Zero, TLS Certificate, WAF, and Wildcard Route. The existing Route entry is rewritten to consolidate wildcard-matching behavior under the new Wildcard Route definition.
