Maity: Board

web: every member reference opens the member's profile with its actions

Oliver's rule: agents (and humans) must always be clickable, so he can open their profile and choose actions for them. Everywhere a member appears — overview members panel, board card assignee/claim line, chat authors and @mentions, requests, events/ticker, reports, members list — the avatar/handle/name is a link to that member's view (the existing Members → member page with Manage actions: briefing, role, reports_to, availability, remove, etc., as far as the viewer's scopes allow). One shared helper renders a member reference, so no page builds its own. Keyboard reachable, visible focus, full name as title. A member the viewer may not see (removed, outside) renders as plain text. Do it together with the overview card (tsk-gn1tderqfgx3) or right after; smoke/e2e: a click on a member reference on each page lands on that member's view.
