Feature: Actor add CLI uses YAML-first persistence path As a developer I want `agents actor add` to route through ActorRegistry.upsert_actor() with yaml_text So that the original YAML text, schema_version, and compiled_metadata are preserved in the database while all CLI flags are honoured Scenario: Actor add calls registry.upsert_actor() with raw yaml_text Given an actor CLI runner And I have an actor YAML-only config file When I run actor add via registry yaml-first path Then registry.upsert_actor() should be called with the raw yaml text Scenario: Actor add with --update flag calls registry.upsert_actor() with update_existing Given an actor CLI runner And I have an actor JSON config file When I run actor add with update flag via yaml-first path Then registry.upsert_actor() should be called with update=True Scenario: Actor add preserves yaml_text for YAML config files Given an actor CLI runner And I have an actor YAML-only config file When I run actor add via registry yaml-first path Then registry.upsert_actor() should receive the original yaml text content Scenario: Actor add preserves yaml_text for JSON config files Given an actor CLI runner And I have an actor JSON config file When I run actor add via registry yaml-first path Then registry.upsert_actor() should be called with the raw yaml text Scenario: Actor add with --set-default sets actor as default Given an actor CLI runner And I have an actor YAML-only config file When I run actor add with set-default flag via yaml-first path Then registry.upsert_actor() should be called with set_default=True Scenario: Actor add with --option applies option overrides Given an actor CLI runner And I have an actor YAML-only config file When I run actor add with option override via yaml-first path Then registry.upsert_actor() should be called with option_overrides containing the override
