Cocoon → Mountain statusBar.update / statusBar.dispose notifications.
Each vscode.window.createStatusBarItem(...) instance fires
statusBar.update with text / tooltip / alignment; statusBar.dispose
removes the item. Sky’s workbench status-bar renderer subscribes to
the downstream sky://statusbar/* family.
Canonical channel prefix is sky://statusbar/ (no hyphen) to match
every other emit site in the statusbar group; the legacy
sky://status-bar/* fork has been retired.
