Spynel 0.12.6

Autostart now has one Enable or Disable button selected from verified native registration state. Each action checks the result and reports failures.

Configuration and channel forms support mouse-wheel scrolling, button and field clicks, caret placement, text selection, and editing through the shared input editor.

Orchestrator workflows use the fixed .spynel/tasks and .spynel/goals directories; the routes setting has been removed. Unused configuration keys are ignored when loading and removed automatically on the next save.

Validated with Go tests and vet, race tests, real terminal input tests, configuration smoke checks, visual captures, npm launcher tests, and a packaged Linux arm64 executable.
