Branch: fix/a2a-namespace-handlers
Commit Message: fix(a2a): implement _cleveragents/namespace/* handlers instead of stubs
Milestone: v3.6.0
Parent Epic: #399

Bug Description

The spec defines three namespace extension methods that must be implemented for server-mode multi-user collaboration:

Extension Method	Purpose
`_cleveragents/namespace/list`	List available namespaces (local, user, org)
`_cleveragents/namespace/show`	Show details of a specific namespace
`_cleveragents/namespace/members`	List members of an org namespace

Actual behavior: All three handlers in A2aLocalFacade return a stub response:

def _handle_namespace_stub(self, params: dict[str, Any]) -> dict[str, Any]:
    return {"status": "not_implemented", "stub": True}

This means any client calling _cleveragents/namespace/list receives {"status": "not_implemented", "stub": True} instead of the actual namespace list.

Expected Behavior (from spec)

Per the spec section Core Concepts > Namespaces:

Namespaces define ownership, scoping, and discoverability of actors, tools, skills, resources, resource types, actions, projects, and plans.

The _cleveragents/namespace/list method should return the available namespaces (local/, <username>/, <orgname>/). The _cleveragents/namespace/show method should return details about a specific namespace. The _cleveragents/namespace/members method should return the members of an org namespace.

Per the spec's A2A extension method table:

| Namespace | _cleveragents/namespace/list, show, members | NamespaceService |

A NamespaceService is referenced but does not exist in src/cleveragents/application/services/.

Code Location

Stub handlers: src/cleveragents/a2a/facade.py — _handle_namespace_stub() method
Missing service: src/cleveragents/application/services/ — no namespace_service.py exists

Steps to Reproduce

from cleveragents.a2a.facade import A2aLocalFacade
from cleveragents.a2a.models import A2aRequest

facade = A2aLocalFacade()
response = facade.dispatch(A2aRequest(method="_cleveragents/namespace/list", params={}))
# response.result == {"status": "not_implemented", "stub": True}
# Expected: {"namespaces": ["local/", "freemo/", ...]}

Subtasks

Implement NamespaceService in src/cleveragents/application/services/namespace_service.py
Wire NamespaceService into A2aLocalFacade (replace stub handlers)
Implement _cleveragents/namespace/list to return available namespaces
Implement _cleveragents/namespace/show to return namespace details
Implement _cleveragents/namespace/members to return org namespace members
Add BDD tests for all three namespace handlers

Definition of Done

_cleveragents/namespace/list returns actual namespace list (not stub)
_cleveragents/namespace/show returns namespace details for a given namespace name
_cleveragents/namespace/members returns member list for org namespaces
All handlers have BDD test coverage
No "stub": True in responses
