feat: vim-motion preset (--vim-motion, off by default) (#147)

* add plan: vim-motion-preset

* feat: add scroll action constants for vim-motion preset

Introduce ActionScrollCenter, ActionScrollTop, and ActionScrollBottom
constants with matching validActions entries and Navigation-section help
descriptions. No default single-key bindings — the upcoming vim-motion
interceptor will be the only way to reach them unless explicitly mapped
by the user.

* feat: add bottomAlignViewportOnCursor and jumpToLineN helpers

Add two diff-pane helpers for the vim-motion preset:
- bottomAlignViewportOnCursor mirrors topAlignViewportOnCursor,
  flipping the offset by viewport height so the cursor lands on
  the last visible row.
- jumpToLineN moves the diff cursor to a 1-indexed line, clamped
  to [1, total], and centers the viewport on the new position.

* feat: wire scroll actions into handleDiffAction

route ActionScrollCenter, ActionScrollTop, and ActionScrollBottom to
their corresponding viewport helpers (centerViewportOnCursor,
topAlignViewportOnCursor, bottomAlignViewportOnCursor). diff-pane only
per plan scope; handleTreeAction is untouched.

* feat: add VimMotion config field

* feat: add vimState struct and transientHint wiring

* feat: add vim-motion interceptor and state-machine logic

* feat: wire vim-motion interceptor into handleKey

Insert m.interceptVimMotion call AFTER handleModalKey and BEFORE
keymap.Resolve, guarded by m.modes.vimMotion. Modal-entry paths (search,
annotate, overlay) consume keys first so modal textinputs receive digits
and letters; the interceptor then preempts normal keymap resolution so
vim chords and count prefixes win over single-key bindings.

Add 8 integration tests covering the precedence matrix: vim-motion off
skips the interceptor; vim-motion on accumulates digits; chord-second
guard and pending-reload guard preempt vim; search/annotate/overlay
modals preempt vim; non-vim keys fall through to normal dispa... (continued)
