Bundle IosevkaTerm Nerd Font Mono as the default Vendored assets/IosevkaTermNerdFontMono-Regular.ttf (~13 MB, OFL) and include_bytes!'d into the shop binary. Removes the DejaVu Sans Mono system-path dependency and gives starship, yazi, helix, nushell their nerd-font icons on any Wayland compositor without a font install step. IosevkaTerm is Iosevka's terminal-tuned variant (narrower cells than default Iosevka) and the Mono cut is what our cell-aligned renderer wants (all glyphs at a single advance, wide chars still 1-cell). Cell dimensions re-tuned for IosevkaTerm at 14 px logical: advance 8.0, height 17.0. May want fine-tuning after eyeball; happy to derive from font metrics via a Shaper::advance_for helper once we care. Binary grows by ~13 MB. Acceptable for a terminal (Alacritty ~10 MB, Ghostty ~30 MB); Iosevka's glyph count is what dominates. LFS or a fetch-at-build script is a follow-up if size matters.
