rebase-branch: mark up range-diffs with ```diff code blocks#157
Conversation
The range-diffs presented to the user in the conflict report and in the PR body are currently wrapped in plain triple-backtick code blocks, which renders them as monochrome text. By using ```diff fenced code blocks instead (one per range-diff entry), GitHub's Markdown renderer applies diff-style syntax highlighting, making additions, deletions, and context lines visually distinct (not full range-diff coloring, but noticeably more readable than plain text). The markup logic is the same sed pipeline used in the "Rebase to Git <version>" PRs at git-for-windows/git, split into two functions: `range_diff_with_markup` runs `git range-diff` with the given arguments and pipes through the markup, propagating failure from range-diff itself; `markup_range_diff` applies just the sed pipeline to already-produced range-diff text on stdin, which is needed for the final summary range-diff that gets annotated with upstream OIDs between generation and rendering. Only the three user-facing range-diff sites are affected (per-skip, per-resolution, and final summary). The correspondence-map generation and AI agent prompts remain untouched.

The range-diffs in the shears-builds PRs (e.g. git-for-windows/shears-builds#12) are currently rendered as plain monochrome text. By wrapping each range-diff entry in ```diff fenced code blocks instead, GitHub applies diff-style syntax highlighting, making them noticeably more readable. This is the same markup used in the "Rebase to Git " PRs at git-for-windows/git.
All three user-facing range-diff sites are updated (per-skip, per-resolution, and final summary); the correspondence-map generation and AI agent prompts are untouched.
