ZacharyZhang-NY c2d1067f0d fix(tui): login picker scrolls in a capped viewport; the moon never clips
Root cause (issues: unscrollable list + half-blocked moon): the stacked
welcome layout gave the menu one Length row per item. With ~30 advertised
providers the vertical layout overflowed and the constraint solver
squeezed every Length — clipping the logo — while rows past the fold were
silently unreachable.

- WelcomeLayout::compute_inner caps the menu to the rows genuinely left
  over after logo/prompt/version, so the chrome never gets squeezed.
- render_menu is now a minimal-scroll viewport: it scrolls only when the
  selection exits it (stable under hover — no re-centering feedback
  loop), draws the picker-style scrollbar, and returns index-aligned hit
  rects (zero Rect for off-screen rows) plus the offset, which AppView
  feeds back next frame.
- Mouse wheel moves the login-picker selection (clamped, not wrapping).

Test: pending_menu_scrolls_and_never_clips_the_moon renders the full
method list at 40 rows and asserts the whole moon (10 braille rows), the
version badge, and that selecting Quit scrolls it into view.

Verified: kigi-tui 6864 tests green, clippy clean.

Key Concepts

  • AppView — owns the welcome screen, agent sessions, and global config
  • AgentView — one per session; owns the prompt, scrollback, tool panes, and modals
  • PromptWidget — text editor component with file search (@), slash commands (/), history search, and paste elements
  • Action/Effect — Elm-style architecture: input → Action → dispatch → Effect → state update
