In a .lin file the description is optional and the comma goes with it, so
"*PLAIN" followed by "A,.5,-.25" is a complete definition. parse only kept
a header that contained a comma, so such a linetype was dropped silently
and a CENTERLTYPE naming it then reported that it was not loaded.
Take the whole header as the name when there is no comma.

Document linetypes referencing ltypeshp.shx glyphs (ZIGZAG, BATTING,
TRACKS) skipped their shape elements whenever the shape file wasn't on
disk — the usual case for traded drawings. The standard ltypeshp
numbers now bridge to the bundled LFF substitute shapes (130 TRACK1,
131 ZIG, 132 BOX, 133 CIRC1, 134 BAT); a resolvable file still wins
with the real SHX glyph.
The element rotation also converted twice: DWG stores radians, the
segment field carries degrees (the .lin unit), and the walker calls
to_radians() — a 180°-flipped second copy rendered at ~3°, folding the
below-baseline half of ZIGZAG/BATTING up onto the line. Convert at the
document boundary.

The SHX reader now serves all three consumers instead of just SHAPE
entities:
- Complex-linetype shape elements stopped being skipped: a document
linetype's Shape{number} resolves its style's shape file (shared path
fallbacks) and draws the real glyph; `.lin` catalog references keep
the file token and look the shape up by name. The converted-LFF
substitute set remains the fallback for anything unresolved.
- Face::Shx renders resolvable on-disk .SHX text FONTS with their real
stroke glyphs: character code → shape lookup, cap height normalised
to the 9-unit space every stroke-font consumer expects, advance from
the interpreter's final pen position, line spacing from the shape #0
above/below header, TTF fallback per missing glyph.
resolve_text_style resolves a style's .shx next to the drawing and
passes the absolute path through; unresolvable names keep their LFF
substitutes. Shapes-only files (no #0 header) are refused as fonts.

A linetype element can carry a `complex` record with no renderable content
(shape #0, null style handle, zero scale) — some DWGs store plain dash
elements that way (e.g. ISO03W100 "ISO dash space"). document_complex_lt
treated any `complex.is_some()` as complex and sent the entity down the CPU
apply_along path, which skips the GPU dash shader and its A-type endpoint
alignment. Gate on *renderable* content (non-empty text, or a shape with a
real shape-file handle) so these fall through to resolve_pattern and dash on
the GPU with proper A-type alignment.

Multilines were drawn with a fixed ±scale/2 two-line guess in the entity
colour, ignoring the MLINESTYLE entirely, so a drawing's custom style (per-
element offsets, colours and linetypes) was lost — a red/yellow multiline
rendered as a white box.
- mline.rs: resolve the MLINESTYLE (by style_handle, then name) and build one
parallel line per element from its offset x scale + justification shift.
- tessellate.rs: special-case MLINE (like Leader) to emit one WireModel per
element in the element's own colour, CPU-dashing every element through
apply_along so the parallel lines stay in phase.
- linetypes.rs: render a drawing's OWN complex linetypes (embedded text/shape),
document definition first and the bundled .lin catalog only as a fallback, so
a file-defined text linetype like PLYN shows its text.
- Run the dash/glyph layout in a local frame (f64 origin subtracted, re-split to
double-single after) so spacing stays precise at UTM coordinates, and pass
tracking = 1.0 so embedded text keeps its letter spacing.
Cargo.lock pins acadrust to the MLINE->MLINESTYLE handle-link reader fix.

Relocate three root-level modules into io/, where they belong by concern:
- update_check.rs -> io/update_check.rs (its own doc-comment notes it
mirrors how crate::io wraps blocking calls in async).
- patterns.rs, linetypes.rs -> io/ (standard resource catalogs parsed
from asset files and populated into the document — IO-shaped work).
Fix the moved files' include_str! paths (one level deeper), add the
mod declarations to io/mod.rs, drop them from lib.rs/main.rs, and
re-point all crate:: references to crate::io::. No behavior change.
