The scope is a view for the prompt, not registry state

/cd stores a scope address on CommandConsole. The prompt, submit(), completion and browsing read through scoped, a ScopedRegistry that tries <scope>.<name> before the name as given. registry keeps resolving full addresses only.

ConsoleServer resolves addresses sent by a mirror, and ConsoleMirror checks whether a namespace already exists. Both must mean the same thing whatever the user entered last, so the scope cannot live in Registry itself.

Considered Options

• Scope inside Registry. One lookup path, but a remote brush.size would resolve to pixelart.brush.size while the frame console sits in pixelart.
• Rewriting the typed line to a full address before classifying it. Completion and the echo would need to undo the rewrite, and root commands would need an escape.

Consequences

• A name in the scope hides the same address at the root. Search inserts full addresses, which still resolve unless the scope holds the same name.
• When the scope's namespace is unregistered, scope falls back to the nearest registered parent and comes back with the namespace, so a mirror reconcile or hot reload does not reset it.
• The scope is not persisted, like the rest of the console (ADR-0005).
