feat(core): advance options/state handling and workflow execution integration

- extend OptionsManager to support multi-namespace option resolution and toggling
- integrate OptionsManager more deeply across Action, ChainedAction, and ActionGroup
- propagate shared runtime configuration through execution layers
- refine action composition model (sequential + parallel execution semantics)
- improve lifecycle consistency across BaseAction, Action, ChainedAction, and ActionGroup
- begin aligning execution flow with centralized context and options handling

wip: routing and root option parsing behavior still in progress
