feat: fold individual hunks in the git views - #28
Merged
Conversation
Tab only expanded or collapsed a whole file in the status view, and the diff shown when opening a commit from the log was plain text that Tab could not act on at all. Both make long diffs a wall of text. Tab on a hunk now folds just that hunk down to its @@ header (marked with a trailing " ..."), leaving its siblings alone. The log-commit diff view gains the same structure: its patch is parsed into files and hunks so each one is foldable, with the commit header and --stat block kept as a plain preamble. A shared PushHunkLines helper renders hunks the same way in both views. Staging and committing are unchanged.

Tabonly expanded or collapsed a whole file in the git status view, and the diff shown when opening a commit from the log was plain text thatTabcouldn't act on at all. Long diffs became a wall of text with no way to focus.This adds per-hunk folding:

Falls back to raw text if parsing yields nothing.PushHunkLineshelper renders hunks identically in both views.Staging and committing are unchanged — stage a hunk with

git_status_folds_single_hunkandgit_diff_view_folds_hunk; full suite passes (698/698). Also verified visually: expanded a file in:git, folded its first hunk, and confirmed the body hid while the next hunk stayed expanded.
