[debugger] add minimum debugger snapshot metadata checks

[watson]

Motivation

Add system-tests coverage for the minimum debugger snapshot metadata we expect on probe-result payloads, while separating body-field checks from ddtags checks so tracer-specific gaps are easier to diagnose and gate independently.

Changes

• add debugger snapshot assertions for root payload properties:
  • service
  • ddsource
• add a separate debugger snapshot test for basic DD tags:
  • host:test
  • debugger_version
  • env
  • version
• validate ddtags across both possible sources:
  • URL query params
  • JSON payload body
• validate that debugger ddtags do not contain duplicate keys across the combined query/body view
• normalize the expected debugger version value for:
  • Java build metadata (+ -> ~)
  • Python release candidate formatting (-rc -> rc)
• gate the remaining unsupported basic_ddtags behavior for:
  • Go
  • Java
  • .NET
  • Ruby

Current failing behaviors

test_payload_basic_ddtags_snapshot

• Go:
  • payload only includes the agent-side baseline tags
  • missing debugger_version, env, and version
• Java:
  • payload duplicates agent_version, env, and version ddtag keys
• .NET:
  • payload duplicates the host ddtag key (host:test and host:weblog)
  • payload is also missing debugger_version
• Ruby:
  • payload duplicates the host ddtag key (host:test and host:weblog)

Workflow

1. ⚠️ Create your PR as draft ⚠️
2. Work on you PR until the CI passes
3. Mark it as ready for review
   • Test logic is modified? -> Get a review from RFC owner.
   • Framework is modified, or non obvious usage of it -> get a review from R&P team

🚀 Once your PR is reviewed and the CI green, you can merge it!

Reviewer checklist

• Anything but tests/ or manifests/ is modified ? I have the approval from R&P team
• A docker base image is modified?
  • the relevant build-XXX-image label is present
• A scenario is added, removed or renamed?
  • Get a review from R&P team
