fix(tree): walk allowed types

[jenn-le]

Description

• adds annotated allowed schema to an alpha TreeNodeSchema API so that annotations are available when walking the schema
• fixes the walkAllowedTypes function by using this new API over the existing childTypes API

[Copilot]

Pull Request Overview

This PR introduces a unified AnnotatedAllowedSchema abstraction for carrying per-type metadata and switches schema traversal and context wiring to use these annotated types. Key changes include:

• Defining the AnnotatedAllowedSchema interface and replacing the old Map-based metadata API with a ReadonlySet<AnnotatedAllowedSchema> returned by normalizeAnnotatedAllowedTypes.
• Refactoring FieldSchemaAlpha, node-kind modules (object, map, array, leaf), and core traversal (walkAllowedTypes/walkNodeSchema) to consume and propagate annotated schemas.
• Updating consumers (e.g., Context, TreeViewConfiguration, SchematizingSimpleTreeView) to pass and handle annotated allowed schemas instead of raw type sets.

• [nitpick] Derive the identifiers from the lazyAnnotatedTypes value to keep them in sync with any filtering or ordering in normalizeAnnotatedAllowedTypes. For example:

this.lazyIdentifiers = new Lazy(
  () => new Set(
    [...this.lazyAnnotatedTypes.value].map(a => a.type.identifier),
  ),
);

this.lazyIdentifiers = new Lazy(() => new Set([...this.allowedTypeSet].map((t) => t.identifier)),

• Add or update the JSDoc above the constructor to reflect that rootSchema now accepts an Iterable<AnnotatedAllowedSchema> (including metadata), not raw TreeNodeSchema instances.

• Enhance the JSDoc for annotatedAllowedTypeSet to explicitly state it returns a ReadonlySet<AnnotatedAllowedSchema> where each entry contains both the evaluated schema and its associated metadata, replacing any mention of the former Map-based return type.

public get annotatedAllowedTypeSet(): ReadonlySet<AnnotatedAllowedSchema> {
