Each screen is now a self-contained `page` block with its own `enter`, `render`, and `key` handlers. Shared logic lives in a `helpers` block mixed into the render context. A `chrome` block renders persistent UI (header, sidebar, footer) before every frame. New context primitives: `go(page)` for transitions, `reload` to re-run the current page's `enter` block, `printable` key binding for text input. `FlowRunner#run_tui` now passes the flow context to TUIRunner so username and other session data are available without reaching into internals.
