Process-level registry of native (host-implemented) tools.
Native tools are registered once by the host — an SDK consumer via
Briyah.registerTool, or the operator in the Nest bootstrap — and are shared
across all users. Per-user/tenant isolation is NOT achieved here (a tool is
global); it comes from the opaque context threaded to the handler and the
existing per-user AppService boundary.
