chore: adopt remaining local development state

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.
