v1.5.2

Changed

• Branding: a distribution that sets mewriteConfig.branding.primaryWordmark now renders that art standalone, replacing the built-in pencil logo entirely instead of rendering beside it. Previously a custom wordmark was always drawn next to the hardcoded pencil and clamped to the pencil's 12x40 footprint, so there was no supported way to show a standalone ASCII/Unicode mark (only logoPath images could replace the pencil). A standalone wordmark is now bounded only by the terminal width; the built-in default still renders beside the pencil within its fixed box. Upstream (no primaryWordmark) is unchanged.
