refactor(ui): share desktop chrome with history

[benvinegar]

Stack

• Depends on feat: add static-first history browsing #979
• GitHub stack: #984

Problem

The first history implementation used a focused raw terminal loop, so interactive history did not share Hunk's desktop-style menu bar, dialogs, theme picker, command authority, or visual language. That made the transition between history and review feel like two separate products.

Approach

• replace the raw interactive loop with an OpenTUI/React LogApp
• reuse Hunk's shared menu bar, dropdown, help-dialog, and theme-selector primitives
• introduce one log command authority for keyboard dispatch, menu hints, help text, and enabled state
• provide focused File, View, Navigate, Commit, and Help menus while omitting review-only Agent, note, file, layout, and mutation actions
• preserve the provider-neutral history seam and add provider-owned alternate-parent review planning for Git and Jujutsu merges
• keep controller state outside React so selection, viewport, search, loaded pages, presentation, and theme survive renderer teardown during commit review
• retain static hunk log unchanged and shell-native

Interaction

• F10 opens the menu bar
• View → Theme reuses the normal Hunk theme picker with live preview
• Enter or clicking a commit id opens its normal Hunk review
• Commit → Open parent supports provider-owned merge-parent selection
• q returns from review to the retained log state, then quits history
• navigation, search, paging, refresh, copy, and menu actions support keyboard and mouse paths

Validation

• bun run typecheck
• bun run lint
• bun run deps:check
• bun run test
• bun run test:integration
• bun run test:tty-smoke
• focused log/controller/command/provider tests: 339 passed during the fix pass
• PTY log integration: 2 passed
• manual tmux checks at 100×28, 80×24, and 45×17
• manually opened the shared menu and existing theme picker in the source-built binary

Tested on Linux with Git, Jujutsu, tmux, and a real TTY. Windows was not tested directly.

Visual evidence

Manual real-terminal validation was performed. Media can be added while this PR remains draft.

Non-goals

• no repository mutation actions
• no permanent diff, status, or file panes
• no conversion of the review AppHost into a permanent multimode IDE host
• no changes to plain static hunk log
