consolidate agent profile runtime details

[tellaho]

Category: improvement
User Impact: Agent profiles present runtime configuration in a cleaner, easier-to-scan Runtime tab.
Problem: Runtime metadata in the agent profile panel had drifted into a redundant, mixed-detail presentation that repeated model/instructions information and did not follow the panel’s existing information architecture. That made it harder to distinguish core runtime facts from configuration provenance.
Solution: Consolidate profile runtime details into the existing icon-row card pattern while preserving the pre-branch provenance copy (Set in Buzz, Inherited from persona, From config file, From ACP session, etc.). Sparse declared-owner cases stay honest instead of rendering empty placeholders.

File changes

desktop/src/features/agents/ui/AgentConfigPanel.tsx
Aligns the runtime config surface with the profile panel card pattern, including copy affordances and read-only lock treatment, while keeping the existing provenance wording.

desktop/src/features/profile/ui/UserProfilePanel.tsx
Updates the profile panel composition so agent-owned runtime details are exposed through the consolidated Runtime tab.

desktop/src/features/profile/ui/UserProfilePanelAgentDetails.tsx
Simplifies the agent-details presentation and removes redundant runtime/instructions dumping from the profile surface.

desktop/src/features/profile/ui/UserProfilePanelFields.tsx
Reuses the shared label/value row treatment for runtime fields and copyable profile metadata.

desktop/src/features/profile/ui/UserProfilePanelSections.tsx
Adjusts the section layout so runtime metadata fits the same visual rhythm as the rest of the profile panel.

desktop/src/features/profile/ui/UserProfilePanelTabs.tsx
Updates tab availability for managed and declared-owned agents so Runtime appears only where it has meaningful content.

desktop/src/testing/e2eBridge.ts
Extends profile/config test fixtures for the runtime metadata states covered by the profile panel.

desktop/tests/e2e/config-bridge-screenshots.spec.ts
Updates screenshot bridge coverage for the consolidated profile panel render path and restored provenance wording.

desktop/tests/e2e/profile.spec.ts
Adds regression coverage for declared-owner runtime visibility and sparse/no-relay-record behavior.

desktop/tests/helpers/bridge.ts
Adds helper support needed by the profile runtime test fixtures.

Reproduction Steps

1. Open an agent profile for a managed agent and switch to the Runtime tab.
2. Confirm runtime metadata uses the same icon-row card pattern as the rest of the profile panel.
3. Confirm provenance text uses the pre-branch wording (Set in Buzz, Inherited from persona, From config file, From ACP session, From environment variable (...)).
4. Open a declared-owner agent with relay runtime data and confirm the Runtime tab shows populated runtime/config rows.
5. Open a declared-owner agent without a relay-agent record and confirm the Runtime tab shows only the verified declared-owner signal instead of empty placeholders.
6. Confirm non-owner viewers do not see owner-only runtime controls or write affordances.

Screenshots/Demos

Runtime-only examples from the final review pass. These are real e2e renders after restoring the pre-branch provenance labels.

Provider / model / env-var / config mix	Normal managed runtime — folded config	Live runtime override + ACP-session provider
Advanced flat list — config-file sourced	Owner → relay agent	Owner → no kind:10100 record

Final gate validation:

• biome check . — clean
• pnpm typecheck — clean
• playwright config-bridge-screenshots --project=smoke — 6/6 passed
