Catch-all for the intermixed residue of the unpushed otko-development work ported into this tree: combinations/console-dock/quick-guide wiring across commands, core, services, views and tests; repo-wide ruff-format normalization; README/CONTRIBUTING updates; and the toolbar default (both toolbars now open in the top area, quick guide text updated). Splitting this further would require hunk-level surgery with low confidence; the preceding commits in this branch isolate the self-contained features.
