feat(eval): add read-only Eval TUI
Wire the interactive TUI over the existing eval command tree for the read-only surface: evaluator and online-eval menus, paginated lists, and resource detail hubs (with a raw JSON view). Mutating commands (create/update/delete/pause/resume) stay CLI-only for now. - New pickers: EvaluatorPicker, OnlineEvalPicker (over the existing listEvaluators / listOnlineEvaluationConfigs Core calls). - New screens: eval / evaluator / online-eval menus, list + get(+json). get hubs reuse the shared ResourceDetailScreen; evaluator kind is derived from the evaluatorConfig union (no type field on the get response), online-eval sampling reads rule.samplingConfig. - RouterScreen gains an `omit` prop so the eval menus hide the mutating subcommands. Without it those items would fall through to the HelpScreen catch-all, which exits the app. - eval routers swap createHelpDefault for withTuiOnEmptyFlagsAndArgs + renderTui, matching harness/runtime/memory. Bare read leaves now open the TUI instead of erroring on a missing required flag; existing leaf tests assert the headless path under --json, matching the memory read-only TUI convention.
