fix(vscode): improve history context menu sizing

[marius-kilocode]

The local History actions menu is currently too compressed to comfortably scan and select its actions. Its rename, export, and delete entries inherit a compact menu treatment that makes this frequently used sidebar menu feel cramped and visually broken.

This gives only the local History session menu a readable minimum width, normal item spacing, and consistent hover and separator treatment. The adjustment is intentionally scoped to menu presentation and does not change session rename behavior or broaden the styling of unrelated context menus.
