<objective>
Deliver a Forge-branded Manus-like agentic transcript inside the main chat UI. Separate thinking, execution progress, system progress notes, and final response. Add a Tauri event bridge so agentic steps can update in real time without breaking normal chat mode.
</objective>

<acceptance_criteria>
- Agentic mode shows a dedicated thinking/plan card immediately after the user prompt.
- Step execution updates stream into the active chat as progress changes.
- Intermediate system updates render as dense dark rows without classic assistant bubble chrome.
- Final response renders as a clean text block with code-copy support and artifact action area.
- Normal chat mode remains unchanged for non-agentic replies.
- New behavior is covered by focused tests for formatting/render gating.
</acceptance_criteria>

<implementation_plan>
1. Create chat-native agentic UI blocks (`AgentThinkingCard`, `AgentStepList`, `AgentSystemMessage`, `AgentFinalResponse`) and refactor `ForgeAgentBubble` to compose them.
2. Extend forgeagent types to support transcript-level system messages and artifact CTA metadata needed by the new UI.
3. Integrate agentic rendering into `ChatView` with conditional transcript blocks and Manus-like assistant presentation.
4. Add a Rust→Tauri event contract for plan and step progress; wire frontend listeners to update live agentic state.
5. Add targeted tests and update `.planning/STATE.md` / summary files after verification.
</implementation_plan>
