Fix child process leak: close ACP runtime after text generation

Wrap makeCursorAcpRuntime with Effect.acquireRelease so that
runtime.close is called as a finalizer when the Effect.scoped
region exits. Previously, the internal runtimeScope (which owns
the spawned child process) was never closed, leaking a process
on every call to generateCommitMessage, generatePrContent,
generateBranchName, or generateThreadTitle.
