workspace: the sidebar Workspace pane is not shown until the first message, so link state and memory drift are invisible on the welcome screen

Summary

The sidebar workspace pane added in #1279 (workspace name, N memories · M not synced, skills synced …, manage URL) is not rendered on the TUI welcome screen. It appears only after the first message of a session. So the moment #1279 set out to create, where a user learns which workspace they are linked to and whether local memory has drifted from it, does not exist until they have already started working.

Observed on altimate-code 0.12.1 (tenant anandtest1) while testing the v0.12.0/v0.12.1 workspace features end to end.

Reproduction

1. In a project linked to a workspace, start ALTIMATE_WORKSPACE=1 altimate-code --yolo.
2. Look at the welcome screen: no Workspace or MCP panel; the right side shows only the "What is Altimate Code" card and tips.
3. Send any message. The sidebar appears with the Workspace pane (pin-1 · 2 memories, manage URL).
4. Run /workspace → Unlink → confirm, then relink from the palette, all before sending a message: the toasts are correct, but nothing on screen shows the binding change until a message is sent.

Recordings: ~/demos/workspace-pilot/recordings/wd1-sidebar-sync-state.mp4 (pane appears mid first turn) and wd2-sidebar-unlink-relink.mp4 (unlink/relink on the welcome screen with no pane).

Why it matters

• The /workspace menu and the sidebar were built as a pair: the pane surfaces the state, the menu acts on it. On the welcome screen only the menu exists, so Status/Refresh/Sync/Unlink are offered before the user has seen anything that suggests they are needed.
• A user opening a checkout to check "am I linked, and to what?" has to send a message to find out, which starts a model turn they may not want.
• The sidebar already updates the pane instantly on onBindingChanged; there is no state reason to hide it before the first message.

Suggested fix

Render the Workspace pane (and the MCP pane) on the welcome screen when a binding is known, using the same Manage.status(dir, { poll: true }) the sidebar poller uses, so link/unlink/rebind and the memory/skill-sync lines are visible before the first message.

@sahrizvi assigning this one to you with the others from the workspace pilot testing. It came out of end-to-end tests of #1279 and #1278 on 0.12.1: the /workspace menu works on the welcome screen, but the pane it was designed to pair with only appears after the first message. The two recordings named in the body show both sides. Low severity, but it undercuts the discoverability that #1279 was written to fix, so I would treat it as part of that feature rather than a new one.
