Pull request overview

Addresses a flaky Playwright test by adding stronger UI state assertions and ensuring workspace tab removals trigger an immediate save.

Changes:

• Trigger flushWorkspaceSave() (when available) after removing a workspace tab instead of only queuing a debounced save.
• Add Playwright assertions to wait for render-mode/style-mode selects and editor content to reflect changes before continuing.
• Simplify the “persists style mode across reload” test assertions to rely on #style-mode value across reload.
