Add Resource Collection example to Everything server

[cliffhall]

Is your feature request related to a problem? Please describe.
@olaservo suggested that we add an example of resource collections. It was prompted by this discussion on the topic.

Describe the solution you'd like
@olaservo has posted a gist that demonstrates the pattern where a single resources/read request

Her example returns multiple ResourceContents with different URIs - useful for modeling collections, indexes, or composite resources.

Resources like the following:

• • demo://collection/summer-specials: Returns all items as separate resources
• • demo://collection/by-category/{category}: Returns items filtered by category
• • demo://collection/item/{id}: Returns a single item (for individual access)

Describe alternatives you've considered
None really. This is a well thought out example, and I think we should add it when the newly refactored Everything server PR is merged.

@claude could you fetch the example from the gist linked in this issue and create a PR based on that code?

Task Complete

I've successfully added the resource collection example to the Everything server based on the gist provided by @olaservo.

What was done:

• Fetched the example code from the gist
• Created a new file src/everything/resources/collections.ts with the collection resources implementation
• Updated src/everything/resources/index.ts to register the new collection resources
• Built the project successfully
• Committed and pushed changes

Summary

The new resource collection example demonstrates the pattern where a single resources/read request returns multiple ResourceContents with different URIs. This is useful for modeling collections, indexes, or composite resources.

Resources added:

• demo://collection/summer-specials - Returns all items as separate resources
• demo://collection/by-category/{category} - Returns items filtered by category (accessories, footwear, skincare)
• demo://collection/item/{id} - Returns a single item for individual access

The implementation includes:

• A main collection resource returning all items
• Three category-filtered collections (accessories, footwear, skincare)
• Five individual item resources (Summer Hat, Beach Towel, Sunglasses, Flip Flops, Sunscreen SPF50)

Each collection returns multiple resources with their own URIs, demonstrating how collections can expose nested items as independently addressable resources.
