Closes FR-139 Most focus-lost issues that close the agent panel in Zen mode stem from panels returning a transient child editor's focus handle from `Focusable::focus_handle`. The Zen-mode check closes the zoomed panel when the focused element is not a descendant of the panel's focus handle, so any focus movement inside the panel that landed outside that child editor looked like the panel losing focus. This PR separates the two roles that handle was serving: - `Focusable::focus_handle` now always returns a stable handle tracked at the panel's root element, used for containment checks (Zen-mode auto-close, `toggle_panel_focus`, dock focus subscriptions). - The new `Panel::activation_focus_handle` returns what should receive focus when the panel is activated (e.g. a filter/commit/message editor) and must be a focus-tree descendant of the root handle. All "focus the panel" callsites in workspace/dock now use it. Migrated panels: `AgentPanel` (including thread views and the toolbar title editor), `CollabPanel`, `GitPanel`, `OutlinePanel`, and `TerminalPanel` (previously delegated to the active pane, so focus in a non-active pane dropped containment). `CollabPanel` activation falls back to the panel root when signed out or collaboration is disabled, since the filter editor isn't rendered in those states. Also fixes duplicate element ids for tool calls with multiple content blocks. Tests: a regression test that clicks tool-call output and focuses the thread title editor while zoomed (both previously closed Zen mode), and a dock-level test asserting the activation handle receives focus on panel activation while the panel root reports containment. Release Notes: - Fixed zoomed panels (e.g. the agent panel in Zen mode) closing unexpectedly when focus moved to elements inside the panel, such as tool call output or the thread title editor.
