[FEATURE] Built-in branch diff badge ("+X −Y") has no hide/disable option — distracting on long-lived branches

Problem Statement

Surface: Claude Code Desktop (FleetView) — the diff-stats badge shown for the active session/branch.

What happens: The badge shows the branch's cumulative committed diff against its base (+1872 −202 vs main), even when the working tree is clean and the current session made no changes. It reads as if there are pending/uncommitted changes when there aren't.

Why it's a problem:

• It conflates two very different things — this session's edits vs. the whole branch's history — under one indicator
• On any branch with real committed history, it's permanently large and noisy, and it can't be cleared without merging/rebasing the branch
• There's no setting, view toggle, or collapse control to hide or re-scope it (confirmed: nothing in settings.json, and a fresh session doesn't reset it)

Proposed Solution

Requested fix (any one would resolve it):

1. A toggle to hide the badge (per-project or global), or
2. Let it show session/uncommitted changes by default, with branch-vs-base as an opt-in or hover detail, or
3. Make the comparison base configurable (merge-base / upstream / none).
