feat(attributes): Add cloudflare.agent attributes to identify agents

[JPeer264]

Description

This adds cloudflare.agent.name (name of the instance name) and cloudflare.agent.class (name of the class name - could be Agent, AIChatAgent or similar).

PR Checklist

• I have run yarn test and verified that the tests pass.
• I have run yarn generate to generate and format code and docs.

If an attribute was added:

• The attribute is in a namespace (e.g. nextjs.function_id, not function_id)
• I have used the correct value for apply_scrubbing (i.e. manual or auto. Use never only for values that should never be scrubbed such as IDs)

If an attribute was deprecated:

• I've followed the policies described in CONTRIBUTING.md

[Lms24]

Hmm I'm wondering if we can use more generic non-cloudflare-scoped attributes here?

• cloudflare.agent.name -> gen_ai.agent.name
• cloudflare.agent.class -> code.function.name (assuming this is about the actual code class name). While a class is not a function, I think this could be close enough here. OTel is quite liberal in the example values for this attribute.

[alexander-alderman-webb]

Is cloudflare.agent.class needed to support any product feature?

[JPeer264]

No it is mainly to create more value on the span itself. Especially if there are more agents running at the same time.

I like your ideas actually

assuming this is about the actual code class name

It is about the class it extends from, so its parent class

[Lms24]

Thanks! Ideally we don't add too many cloudflare(-or-any-other-lib/framework/plaform)-specific attributes when there are reasonable, more general replacements. Lmk if you wanna continue with any of these attributes :)

Totally agree. In this case I missed the alternatives.

I'll close this as both of the alternatives are already in
