Jiayuan Zhang 977b0c0558 feat(agents): show profile card on agent avatar hover (#1577)
* feat(agents): show profile card on agent avatar hover

Hovering an agent avatar now opens a preview card with name, status,
runtime mode + connectivity, model, skills, and owner. Wired through
the shared ActorAvatar wrapper so every render site gets it; opt-out
via disableHoverCard in pickers and the agent's own detail header
where the card would be redundant or interfere with click selection.

* fix(agents): keyboard-focusable hover card + opt out on settings avatar

- Make the agent profile-card hover trigger focusable (tabIndex=0 with
  visible focus ring), so keyboard users can open the card. Drops
  cursor-default so the trigger inherits the parent control's cursor
  instead of fighting it.
- Disable the hover card on the agent settings avatar — it's a
  click-to-upload target on the agent's own settings page, where the
  card would be redundant and the trigger conflicted with the upload
  affordance.

* fix(agents): scope hover-card tab stop to standalone avatars only

Detect a focusable ancestor (link/button/role=button/tabindex>=0) at
mount and only flip the agent profile-card trigger to tabIndex=0 when
none exists. Avatars rendered inside an existing focusable parent (issue
list rows wrapped in AppLink, button-style cards, etc.) keep the trigger
unfocusable so they don't add redundant nested tab stops or bloat
keyboard navigation. Standalone avatars (e.g. comment author, issue
detail meta) remain keyboard-accessible with a focus-visible ring.
