Subject: [PATCH] feature: allow copying ref names from commit info panel

Adds a small copy button next to each ref pill in the commit info
panel. Clicking it copies the ref name (e.g. "main", "origin/feature")
to the clipboard, matching the existing copy affordance on the SHA row.

CommitRefsPresenter gains an optional Decorator styled property. When
set, the presenter renders that single decorator instead of iterating
DataContext.Decorators. The existing multi-decorator path is unchanged,
so the Histories grid still renders refs the same way it did before.

CommitBaseInfo's REFS row, previously a single CommitRefsPresenter
rendering all decorators in one custom-drawn run, is now an
ItemsControl over Decorators where each item is a single-decorator
presenter plus a copy Button. The Button picks up Avalonia's standard
tooltip and hover styling. Wrap now happens between pill+button
groups instead of inside one continuous presenter.

Pill geometry, icons, fills and outlines are unchanged. The Histories
grid is intentionally untouched.
