[FEATURE] Agent view: stable sort mode (fixed order + status as indicator) to stop constant reordering

Problem Statement

In the claude agents view, sessions are constantly reordered as I work. The list pins running sessions to the top and orders the rest by start time, so the moment a session flips in or out of running it jumps between groups and everything shifts position. I lose track of where a given session was, and positional muscle memory never holds.

The current comparator (from the 2.1.170 bundle) pins running first, then sorts the rest by start time descending — there's no branch that reads a stable key, which is the root of the reshuffling.

Proposed Solution

Add a stable sort mode for the agent view: keep sessions in a fixed order (e.g. creation/insertion order) and rely on the existing status indicator (text/colour) to convey state, instead of using status as the primary sort key. Sessions would stay put; I'd read their state from the status column rather than from their position.

Expose it as either:

• a settings key, e.g. agentViewSort: "stable" | "running-first" (default running-first to preserve current behaviour), and/or
• a toggle key in the view to cycle sort modes.

Related

• #58243 asks for the inverse within the current grouping model (sort each group by most recently updated rather than created). Both are really requests for configurable agent-view sort — a stable mode and an updated-time mode are two options of the same toggle, so it may make sense to address them together.
• #60241 asks to expose AgentView as a rebindable keybindings context, which a sort-mode toggle key could plug into.
