feat(ui): make history automatically responsive

[benvinegar]

Stack

• Depends on refactor(ui): share desktop chrome with history #983, which depends on feat: add static-first history browsing #979
• GitHub stack: #984
• Approved responsive mock: https://sideshow.sh/p/eAsZCIw7mf4

Problem

The history stack still exposed static and interactive modes as separate user experiences, and its interactive rows used a conventional left-to-right terminal-log layout. Users should be able to type hunk log once and get the right experience for their environment, with information density that responds automatically to available space.

Approach

• make plain hunk log open the interactive desktop history browser when stdin and stdout are terminals
• preserve automatic complete static output for pipes and redirection
• add --static to force static output on a terminal, paging only when needed
• retain hidden --interactive parsing as a compatibility alias without documenting a second workflow
• replace interactive medium/compact controls with one width-driven responsive projection
• use a GitHub-inspired hierarchy: title, description, author/date/decorations on the left; commit ID and secondary merge state aligned right
• progressively remove description, date, and secondary state as width contracts
• reserve the right-side ID and a minimum title budget even for adversarial multi-lane graphs
• preserve display-cell-correct clickable IDs, themes, Git/Jujutsu providers, bounded loading, menus, and review-return state

Static --oneline and --format remain available because they control shell output rather than creating competing interactive applications.

Validation

• full test suite: 2,186 passed, 9 skipped
• log PTY integration: 6 passed
• bun run typecheck
• bun run lint
• bun run check:docs
• bun run deps:check
• changed-file formatting and git diff --check
• independent review of the implementation and follow-up fixes
• manual tmux validation at 100×24 and 45×18
• manually verified automatic TTY launch, responsive resize, and forced static output

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

Visual evidence

The approved responsive design is available at https://sideshow.sh/p/eAsZCIw7mf4. Real-terminal media can be added while this PR remains draft.

Non-goals

• no repository mutation actions
• no alternate interactive density modes
• no changes to provider-owned history or review semantics
• no removal of static formatting controls used by pipes and scripts
