Converts a source-map from/to different formats and allows adding/changing properties.

Retrieves a name:pathname Map for a given workspaces config

A sorted list of key-value pairs in a fast, typed in-memory B+ tree with a powerful API.

The Map & WeakMap data structures as a reactive signals.

Wrap zod validation errors in user-friendly readable messages
