 - persisted ask settings are migrated to the current schema version, validated, and normalized before use
 - config schema migrations preserve user-provided values and add new defaults only when fields are absent
 - replay payload lookup scans only the current session branch and revalidates payloads before use

+- invalid persisted keymaps fall back to default keymaps for the current session without discarding valid behaviour, notification, or answer settings
 - invalid notification channels are skipped and fall back to the default bell channel if none are valid
 - ask settings behaviour and notification enabled changes persist immediately from the settings list
 - when the ask config file is missing, the first ask use writes a default persisted config snapshot under `~/.pi/agent/extensions/`
