Stefan Haller da4dfa17d5 Render the custom-patch secondary pane through the pager, via a real git diff ... The secondary pane showed the custom patch with a bespoke in-memory render (PatchBuilder.RenderAggregatedPatch / FormatView). That had two problems: it could never be fed to a pager the way the main view's diff is (a stdin pager might have worked, but an external diff tool like difftastic, which diffs two files rather than a unified diff, could not), and its hand-rolled hunk/context handling differed subtly from git's. Materialize the patch instead as two real file trees under a temp dir — a/ holds each patched file's "from"-side content, b/ that content with the patch applied — and render it with `git diff --no-index`, reusing the exact pager wiring the main view uses (stdin pager, external diff, or git's own colour as the raw fallback). `--no-index` honors both GIT_PAGER and --ext-diff, so every pager type now renders the custom patch like any other diff, and git computes the context, fixing the quirks. Because the secondary is now an async diff task, the post-removal selection reveal (which rides a task's restore) finally takes effect. The trees are named a/b so that with --no-prefix the diff shows the real repo-relative paths; added files are seeded empty in a/ so they pair up and show their real paths rather than git's directory-comparison "added in b" form. The patch builder owns the temp dir's lifetime (created on Start, removed on Reset) and bumps a generation counter on every change, so the trees are rebuilt only when the patch actually changes — covering the focused-main view and the old explorer alike, without rebuilding on mere navigation.
