HAL9000 86525a4ba4 fix(schema): add BDD scenarios and fix lint for server-qualified name validators
Add BDD test scenarios for server-qualified name acceptance in:
- features/actor_schema.feature: Accept/reject scenarios for server:namespace/name format
- features/skill_schema.feature: Accept scenarios for server:namespace/name format
- features/consolidated_tool.feature: Accept scenarios for server:namespace/name format

Also fix lint issues in the previous commit:
- Remove trailing whitespace from actor/schema.py docstring
- Split long NAMESPACED_NAME_RE line in skills/schema.py

Scenario: Execute without prior activate still works via registry lookup
Given a tool registry
And a registered tool spec named "test/no-activate" with an adder handler
And a tool runner for the registry
When I execute tool "test/no-activate" with inputs {"a": 5, "b": 3}

Then the tool result should be successful
And the tool result output should contain key "result"
# ---- List Tools With tool_type Filter ----
Scenario: List tools with tool_type filter returns matching tools
Given a tool registry
