Replace 3-component hashline system (separate hashline_edit tool + edit disabler hook + OpenAI-exempted read enhancer) with 2-component system that directly overrides the native edit tool key, matching the delegate_task pattern. - Register hashline tool as 'edit' key to override native edit - Delete hashline-edit-disabler hook (no longer needed) - Delete hashline-provider-state module (no remaining consumers) - Remove OpenAI exemption from read enhancer (explicit opt-in means all providers) - Remove setProvider wiring from chat-params
