- Add detailed console.log statements in protocol.ts getMetaTypes() and getMetaItems()
- Fix protocol initialization to include feed service callback
- Log services registry availability, metadata service access, and item counts
- This will help diagnose why AI metadata (agents/tools) are missing in Studio sidebar after Vercel deployment

- Create local integration test to verify protocol metadata service logic
- Test confirms getServicesRegistry callback works correctly
- Test confirms metadata service methods are called and items are merged
- Add comprehensive TEST_REPORT.md documenting test results and expected behavior
- All tests pass, backward compatibility maintained

**Root Cause:**
Protocol callback captured PluginContext during ObjectQLPlugin.init(), but MetadataPlugin
registers its service AFTER ObjectQLPlugin. This meant ctx.getServices() returned a snapshot
without the metadata service, causing agents/tools to be invisible in Studio sidebar.

**Fix:**
Changed protocol initialization to access kernel.context.getServices() dynamically at request
time instead of capturing ctx.getServices() during init. This ensures the protocol always
accesses the live services registry with all registered services including MetadataService.

**Changes:**
- ObjectQLPlugin: Use ctx.getKernel() to get kernel reference, access services via kernel.context
- Protocol: Removed diagnostic logging (no longer needed)
- AIServicePlugin: Removed diagnostic logging
- MetadataPlugin: Removed diagnostic logging

**Verified:**
- Protocol now accesses services dynamically at runtime
- MetadataService is accessible even though it registers after ObjectQLPlugin
- Agents and tools should now be visible in Studio sidebar on Vercel

Replace direct access to kernel.context (private property) with public
kernel.getService() method. The protocol now probes for known services
at runtime to build a fresh service map, ensuring metadata service is
accessible when needed.

The previous fix attempted to probe for services using a hardcoded list,
which missed services not in the list. The correct solution is simpler:
ctx.getServices() returns a fresh snapshot of ALL services each time it's
called (see kernel.ts:144-145), so we can just pass it as a callback.

This ensures the protocol has access to all services registered after
ObjectQLPlugin's init() phase, including metadata service (for agents/tools)
and AI service, which are registered by later plugins.

Root cause: Protocol was capturing ctx.getServices() result during init()
instead of calling it at runtime. Now fixed by passing the function itself.
