## Description

Closes [APP-3595](https://linear.app/warpdotdev/issue/APP-3595).

The conversation details side panel was previously only visible for
cloud Oz runs (a `TerminalView` had to expose an `AmbientAgentTaskId`).
Local Warp Agent conversations had no way to surface the same metadata
even though `ConversationDetailsPanel` and
`ConversationDetailsData::from_conversation` already supported that case
on web.

This PR makes the pane-header info button and the side panel available
for **any active AI conversation in a `TerminalView`** (cloud Oz runs
continue to work unchanged). Task-only sections (Run ID, Environment
details, setup commands, error message, inference/compute credit split)
stay hidden when there's no backing `AmbientAgentTask`; everything else
(status, working directory, conversation ID when persisted, run time,
credits, source prompt, artifacts, harness, creator) renders from the
active `AIConversation`.

### Behavior summary

- **Cloud Oz runs**: unchanged. Info button in pane header, auto-open on
`SessionReady`, all existing fields rendered.
- **Cloud non-Oz runs (Claude / Gemini)**: unchanged. Task-mode panel as
today.
- **Local AI conversations (native)**: a new info-button toggle is
visible whenever there's an active conversation and AI is enabled.
Clicking opens the panel populated from the active `AIConversation`.
Task-only sections are hidden because the data isn't available.
- The panel does **not** auto-open for local conversations — it
only opens when the user clicks the toggle. Auto-open behavior on
`SessionReady` is still scoped to cloud mode.
- The panel refreshes on
`BlocklistAIControllerEvent::FinishedReceivingOutput` for any active AI
conversation (previously: only when the view was an ambient agent), and
on relevant `BlocklistAIHistoryEvent` updates so
streaming/status/artifact changes flow through while the panel is open.

### Key code changes

- `app/src/ai/conversation_details_panel.rs`: lifted the
`#[cfg(target_family = "wasm")]` gates on `from_conversation`,
`CreatorInfo::from_uid_fallback`, and the `UserUid` / `UserProfiles`
imports so the helper compiles on native.
- `app/src/terminal/view.rs`: added
`TerminalView::has_active_local_ai_conversation` and
`TerminalView::can_show_conversation_details_ui`, used the broader
predicate in the render gate, and broadened the refresh hooks.
- `app/src/terminal/view/ambient_agent/view_impl.rs`: generalized
`fetch_and_update_cloud_mode_details_panel` to fall back to the active
`AIConversation` when there's no task ID.
- `app/src/terminal/view/pane_impl.rs`: lifted the toggle button
rendering out from under the `FeatureFlag::CloudMode` arm in
`render_header_actions`.
- `app/src/ai/conversation_details_panel_tests.rs`: added a unit test
asserting that `from_conversation` populates the local-conversation
fields the details panel renders (working directory, title, source
prompt, `LocalConversation` credits, `Conversation` mode).

## Testing

Manually tested:
https://www.loom.com/share/1ca886583b3340ea94842ce7202a3c57

- Added `test_from_conversation_populates_local_conversation_fields` in
`app/src/ai/conversation_details_panel_tests.rs`. All 5 tests in the
`conversation_details_panel` module pass.
- `cargo check -p warp --lib` succeeds.
- `cargo clippy -p warp --lib --tests --no-deps -- -D warnings`
succeeds.
- `cargo fmt -p warp` applied.
- Manual smoke test (recommended for reviewers): start a local Warp
Agent conversation in a terminal pane and verify the info button appears
in the pane header, opens the side panel populated with the
conversation's title, status, initial query, run time, credits, working
directory, and conversation ID (when persisted). Compare to a cloud Oz
run for parity.

changes.

## Agent Mode

- [x] Warp Agent Mode - This PR was created via Warp's AI Agent Mode

## Changelog Entries for Stable

CHANGELOG-IMPROVEMENT: Conversation details side panel is now available
for local Warp Agent conversations, not just cloud Oz runs. Click the
info button in the pane header to open it for any active AI
conversation.
