Make it easier to open a workspace on hover

Problem to solve

Currently, we hide most workspaces action buttons within the more actions dropdown, which is visible only on click after hovering on a workspace entry. Although the new workspace name (e.g. yellow-giraffe-c5e97000) is clickable and opens the workspace itself, it's not as discoverable at the moment.

Workspace Name	Stopped Workspace

Proposal

Similar to the more actions button, we can surface more actions on workspace hover to make it easier for the user to perform the most prominent actions like Open Workspace (see Proposal A).

CURRENT (DEFAULT)	CURRENT (HOVER)	PROPOSAL A	PROPOSAL B

Other small specs:

1. Action button can always read Open Workspace to match usage on stopped workspace page.
2. The Last Active column can be hidden on hover to make room for the action buttons to surface.
3. We can start by surfacing only the Open Workspace button.
4. Proposal B shows how we could surface one more action for deleting workspaces or pinning workspaces.

See also relevant specs, in case these can help.

Start by locating the workspace list UI and reviewing the linked Figma spec, especially Proposal A and Proposal B. Confirm which hover behavior is intended, then make the Open Workspace action discoverable on hover while checking the Last Active column and existing workspace actions. Done means the chosen design works for active and stopped workspaces and matches the stated button wording.
