feat(ui): make configuration pickers compact and inline - #2182

Note

Medium Risk
Large UX change to model/provider configuration and selection lifecycle in interactive mode; behavior is heavily tested but affects a core user path.

Overview
Replaces the tabbed full-pane configuration overlay with compact inline pickers mounted in the prompt area; closing or canceling restores the editor draft instead of hiding an overlay.

Models, providers, and MCP each open as a single-purpose picker (no tab bar or app.configuration.previousTab). Lists use a new inline menu layout: bordered search-first rows, soft selection (bold label on a blended band), and right-aligned trailing status (provider, require sign in, current).

The models picker adds effort/reasoning controls on each row (■/□ cluster, ←/→ on the highlighted row when search is empty; arrows edit search when it is not), Enter applies model plus explicitly adjusted effort while keeping focus until both complete, per-million-token pricing for the selection, signed-in-first ordering with Prime Inference pinned when authenticated, and updated search ranking.

Docs and keybindings reflect picker-specific behavior; onboarding dismisses the splash before opening model selection inline.

Note

Render configuration pickers inline in the editor area with compact layout

• Replaces the full-pane overlay configuration menu with inline pickers mounted in the editor container. Provider, model, and MCP pickers now render separately without tab chrome.
• Removes tab-based navigation (app.configuration.previousTab, switchTab) from the configuration menu; Tab/Shift+Tab now stay within the active picker.
• Adds inline rendering branches to MenuPanel, MenuRow, MenuList, MenuSearchInput, OAuthSelectorComponent, and ModelSelectorComponent with compact one-row items, right-aligned trailing metadata, and reduced padding.
• Adds inline effort controls (filled/empty squares with left/right cycling) and responsive pricing details to ModelSelectorComponent; selection callback now carries an optional thinking level only when explicitly edited.
• Model selection and effort application are now guarded by a busy state; the menu stays open until both operations succeed, and focus/draft text is preserved across authentication and failures.
• Risk: ConfigurationMenuTabBar, app.configuration.previousTab keybinding, and ConfigurationMenuComponent.switchTab are removed; any out-of-tree consumers of these symbols will break. applyThinkingLevel now returns Promise<boolean> instead of void.
