The v1 standalone installer makes processkit independently installable,
updatable, verifiable, and removable. Release policy is carried by the
signed processkit distribution rather than hard-coded into downstream
tools.

`v1.0.0-alpha.5` implements the local lifecycle, exact-version bootstrap,
native runtime diagnosis, MCP supervision, and trust boundary. Four-platform
publication requires locally produced and natively smoke-tested outputs from
each supported host architecture; no hosted build service is used.
