Summary

• Marking reviewed advances to the next file. Pressing the shortcut used to leave the viewport stranded: with "hide reviewed" on, CodeView remounts and restored a stale scrollTop (landing at the top or on an unrelated file); with it off, the file just collapsed in place. Now it scrolls to the next file's header like n does. The hide-reviewed path scrolls after the remount via a pending target instead of the saved offset; the collapse path waits two frames so the target offset isn't computed from pre-collapse heights.
• Fix: the shortcut could mark the wrong file. Right after n, the previous file's sticky header is still in the DOM at about −6px while the current header sits 9px below the scroll area's top, and getCurrentFile only allowed 8px, so it picked the previous file. Tolerance is now 24px (CURRENT_FILE_HEADER_SLOP_PX).
• r marks a file reviewed (matches the "Reviewed" label). m still works as an undocumented alias.
• o expands or collapses the current file, so a reviewed (auto-collapsed) file can be opened without un-marking it. Collapsing a reviewed file no longer records a manual collapse, so un-marking it later expands it again.
• Vim-style scrolling: j/k (60px), d/u (half page, Vimium-style since Ctrl-d/u belong to the browser), gg/G (top/bottom). Single presses scroll smoothly; key repeat scrolls instantly.
• Shortcuts dialog and tooltips updated.
• Fix: scroll position wasn't restored on page reload (pre-existing; v0.7.0 does the same). The restore ran two frames after mount, before CodeView had laid out its content, so scrollTop clamped to 0. It now retries each frame until the content is tall enough (3s deadline) and stops if the user scrolls first.
• Tidy-up: vim keys folded into the keydown switch, scrolling via CodeView's containerRef, a stable empty set so marking reviewed doesn't re-run the scroll-restore effect, toggleReviewed returns the new state, one afterLayout() helper, and comments that restated the code removed.

Testing

• oxlint and oxfmt --check pass; vite build succeeds.
• Verified the release build with headless Chrome on a 6-file fixture and on this repo's diff since v0.5.0, with "hide reviewed" both on and off:
  • n n + scroll + r marks the file in view (it used to mark the previous one); repeated r walks c → d → e → f.
  • p back to a reviewed file, o expands it while it stays reviewed, o collapses it, r un-marks it and it expands.
  • j/k/d/u move by the expected amounts; G reaches the exact bottom (166,605px on the large diff), a single g does nothing, and gg returns to the top.
  • Reload restores the exact offset: 4321 / 21,605px on the fixture, 4321 / 86,420px on the large diff (previously 0).
