test(coverage): add Behave BDD tests to improve unit test coverage across 53 source modules
Add 53 new .feature files and corresponding step definition files targeting
uncovered lines identified in build/coverage.xml. Fix AmbiguousStep conflicts
in 7 pre-existing step files by disambiguating step text.

New tests cover: ACP clients/facade, actor CLI/config, application container,
ACMS service/strategies, async worker, automation profile CLI, autonomy
guardrail, bridge, change model, config CLI/service, context service,
cross-plan correction, database models, decision service, decomposition
clustering/service, discovery handler, langchain chat provider, langgraph
nodes, materializers, multi-project service, plan apply/CLI/lifecycle/model/
preflight/resume/service, PostgreSQL analyzer, project CLI/context CLI,
provider registry, reactive application/route, repositories, resolver handler,
resource registry service, resume model, retry patterns, sandbox protocol,
server CLI, skill CLI/service, skills registry, subplan execution/service,
system CLI, UKO loader, UoW, and YAML template engine.

Feature: Handler resolver edge-case coverage
As a developer maintaining the handler resolution subsystem
I want to exercise the uncovered error paths in resolve_handler
So that every branch in resolver.py is tested
Background:
Given the handler cache is cleared
# --- Lines 72-73: empty module_path or class_name after split ---
Scenario: Reject handler reference with empty module path
When I try to resolve handler ref ":SomeClass"
Then a handler resolution error should be raised with message "both module path and class name are required"
Scenario: Reject handler reference with empty class name
When I try to resolve handler ref "some.module:"
Then a handler resolution error should be raised with message "both module path and class name are required"
# --- Lines 84-87: generic Exception (not ModuleNotFoundError) during import ---
Scenario: Generic exception during module import raises HandlerResolutionError
Given a module import that raises a generic RuntimeError
When I try to resolve the rigged handler reference
Then a handler resolution error should be raised with message "Error importing handler module"
# --- Lines 99-102: Exception during handler class instantiation ---
Scenario: Exception during handler instantiation raises HandlerResolutionError
Given a module whose handler class raises TypeError on init
When I try to resolve the rigged handler reference
Then a handler resolution error should be raised with message "Cannot instantiate handler"
# --- Lines 106-107: instantiated object does not satisfy ResourceHandler protocol ---
Scenario: Handler class not satisfying ResourceHandler protocol is rejected
Given a module whose handler class does not satisfy ResourceHandler
When I try to resolve the rigged handler reference
Then a handler resolution error should be raised with message "does not satisfy ResourceHandler protocol"
# --- Whitespace-only reference triggers line 53-54 ---
Scenario: Whitespace-only handler reference is treated as empty
When I try to resolve handler ref " "
Then a handler resolution error should be raised with message "must not be empty"
