vt: decode UTF-8, render box-drawing/arrow glyphs procedurally
The editor's gutter '│' (U+2502) appeared as '???' — write_bytes fed
each UTF-8 byte to the state machine, which mapped every byte >= 0x80
to '?', and the Latin-1 font has no box-drawing glyphs anyway.
- vt.write_bytes now decodes UTF-8 sequences; printable non-ASCII
dispatches to the glyph path instead of the byte parser.
- gop: unicode_glyph_bits() procedurally rasterises box-drawing
(U+2500-257F light/heavy/double), arrows (U+2190-2193) and the em
dash (U+2014) — pure geometry, no font data needed; blit_glyph falls
back to it for ch >= 256.
Verified via framebuffer dumps: editor gutter │ renders as a vertical
line, help screen ═ separators and ←→↑↓ all render as lines (no '?').
Shell banner em dash renders too.
