* feat: improve agent and quick model picker behavior
* fix: keep the active model highlighted in the quick picker
* feat: streamline mobile model selection
Open the full mobile model picker directly and remove the intermediate controls drawer so mobile model changes follow the same core selection flow as desktop.
Add inline thinking-mode chips that show each model's remembered or default variant, apply model and variant together on tap, and fall back to a dedicated overflow panel for larger variant sets. Also keep favorites and recents searchable on mobile and fix clearing remembered default variants so the picker stays consistent across sessions.
* fix: polish desktop model picker interactions
Stabilize desktop model picker behavior by keeping keyboard and hover selection in sync, preventing hover-driven closes, and making the footer hints visually stable.
Also make quick-picker thinking mode changes apply consistently when switching plan/build or agent mode inside the picker, clamp left/right variant cycling at the ends, and keep thinking feedback visible even when the selected variant cannot move further.
* fix: condense mobile model picker rows
Tighten the mobile model picker to use a more compact, consistent row layout across favorites, recents, and provider sections while keeping context length and capability icons easy to scan.
Also preserve inline thinking-mode selection, improve metadata spacing, and keep the mobile controls readable without reintroducing the heavier drawer-based flow.
* fix: include all primary-like agents in picker cycling
Keep desktop Tab cycling and mobile tap cycling aligned with the rest of the selection UI by including agents marked as all or left unset, not just strict primary agents.
* fix: preserve remembered agent variants in picker flows
* Fix model picker variant restore
* Polish favorite model drag handle
* Fix Korean model picker locale
