[Workspaces/UX] Session list silently filtered when inside workspace context #27286

Description

Description

When inside a workspace context, the /sessions list is automatically filtered to only show sessions belonging to that workspace. This filtering happens silently with no visual indication, causing users to lose track of sessions they know exist.

While a toggle command exists in the command palette (app.toggle.session_directory_filter), users don't know:

1. That filtering is active
2. That this toggle exists
3. How to find it

Suggested Fixes

Option A: Add visual indicator when filtering is active

In the session list dialog, show something like:

Sessions (filtered to current workspace)  [Press X to show all]

Option B: Add "Show all sessions" option in session list

Location: packages/opencode/src/cli/cmd/tui/component/dialog-session-list.tsx

Add an action to the session list dialog:

{
  command: "session.show_all",
  title: "show all",
  onTrigger: () => {
    kv.set("session_directory_filter_enabled", false)
    sync.session.refresh()
  },
}

Option C: Don't filter by default

Change the default from true to false:

if (!kv.get("session_directory_filter_enabled", false)) return { scope: "project" }

Workaround

Open the command palette and search for "session directory filter" to toggle filtering off.
