Wires the ACP runtime plugin into the published CLI (RUNTIME_PLUGIN_IDS in
tsup.config) and the on-demand BUILTIN_PLUGINS catalog (experimental), matching
the untrusted-subprocess security posture. Adds the Risk S1 default-policy
safety: an acpAllowUnrestricted acknowledgement (default false) — without it, a
blanket allow on a sensitive category is escalated to approval rather than
auto-approved under the allow-all default policy, applied in both the permission
floor and fs write gating. Adds docs/acp-contract.md (launch/readiness +
failure taxonomy), a README with the AGENTS.md-required upstream evidence
(SDK repo/docs/release/integrity), a bundle-output test for the staged plugin,
and a @runfusion/fusion minor changeset. Package green at 179 tests.
