[fix] Enable agent rename on the onboarding playground [AGE-3954]

[ashrafchowdury]

Context

On a new workspace with no agents, the playground onboarding showed the agent name as a plain "Agent" label you could not rename. Double-clicking it only selected the text, so it looked editable but nothing happened. Renaming worked again after a reload, which is what made this read as a flaky regression.

The header resolved the agent only from currentWorkflowAtom, which reads the app id out of the URL. Onboarding runs on the project-level playground route (/w/../p/../playground) with no app_id segment, so that atom returns null. The header then fell back to a static, non-editable label showing a hardcoded "Agent" string (not even the real agent name). Opening a saved agent at /apps/<id>/playground puts the id back in the URL, which is why a reload appeared to fix it.

What to QA

• On a workspace with no agents, open the playground onboarding with a saved agent selected. The header shows the real agent name, not a hardcoded "Agent", and a pencil appears on hover.
• Rename it there with the pencil or a double-click, then press Enter. The new name sticks in the header.
• Reload the page. The new name is still there, which confirms the rename reached the backend and did not just update local state.
• Regression: open a saved agent at /apps/<id>/playground and rename it. Behaves exactly as before.
• Regression: in the onboarding before you click "Create agent" (the local draft), the name is still a plain label with no pencil. That is expected, not a miss.

📝 Walkthrough

Walkthrough

The playground header now supports inline agent renaming when the current workflow is unavailable by resolving a persisted root workflow and artifact name. The inline name affordance also adds pointer styling, a rename tooltip, and hover opacity behavior.

Changes

Agent naming flow

Layer / File(s)	Summary
Root workflow rename resolution web/oss/src/components/Playground/Components/PlaygroundHeader/index.tsx	The header derives the root workflow and artifact name, using a persisted non-local-draft workflow as a fallback rename target.
Inline name rendering and affordance web/oss/src/components/Playground/Components/PlaygroundHeader/index.tsx, web/oss/src/components/EntityIdentity/AgentNameInline.tsx	The resolved name is rendered through inline editing when available, with updated pointer, tooltip, and hover opacity styling.
