feat(console-web): redesign Invoke as chat-like current run console

[potter-sun]

Background

Invoke currently behaves like a developer runtime workbench. The intended product experience is a chat-like execution surface for starting and observing the current member run, with diagnostics available but not dominant.

Scope

• Make the main Invoke surface prompt-first and response-first.
• Move composer and primary Invoke action into the main console path.
• Show current run status, run id, command id, duration, and Open in Runs as a compact strip.
• Collapse advanced target, headers, contract, and raw event details by default.
• Reduce mode sprawl into Conversation, Timeline, and Events views.
• Keep typed command endpoints honest with a typed payload editor instead of pretending all inputs are chat prompts.

Acceptance Criteria

• A newly bound member can be invoked from a single obvious composer.
• Streaming output is visible in the default view.
• Current run identity separates run id, command id, actor id, and member id.
• Open in Runs is enabled only when a run id exists.
• Advanced diagnostics do not dominate the default path.
• Tests cover chat endpoint and typed command endpoint behavior.

Verification

• npm --prefix apps/aevatar-console-web run tsc
• npm --prefix apps/aevatar-console-web run build
• npm --prefix apps/aevatar-console-web run test -- --runInBand src/pages/studio/components/StudioMemberInvokePanel.test.tsx src/pages/studio/components/StudioMemberInvokePanel.currentRun.test.ts src/pages/studio/components/studioInvokeUi.test.ts
