feat(claude): default qualified macOS and Linux targets to Runner

Enable Intel Mac, Linux x64, and Linux ARM64 after passing package consumers and the bounded API task/continuity pairs. Keep unsupported targets, overrides, and explicit Legacy choices intact.

+Legacy. The runner override is in Advanced. Ordinary Claude models default to `claude-opus-5-5`; explicit models
 and provider routing remain authoritative. Existing agents keep their saved runner. Converting an existing Claude, Codex, or OpenCode agent selects its
 corresponding provider, preserves compatible models, credentials, workspace,
 and instructions, and resets execution sessions while retaining run history.
