Add three research documents on parser correctness fundamentals
- graphics-state-tracking: full q/Q stack, text state operators, color
space tracking, ExtGState keys, clip path management, CTM concatenation,
blend mode/soft mask visibility, Form XObject isolation, GraphicsState
Rust struct with is_text_visible implementation
- cmap-format-and-cid-encoding: CMap file structure, codespace range
scan grammar, bfchar/bfrange/cidchar/cidrange semantics, usecmap
inheritance with predefined CJK CMap inventory, mixed-length parsing
state machine, ToUnicode defect handling, Rust CMap struct design
- content-stream-concatenation: multi-stream concatenation with 0x0A
injection, continuous graphics state across boundaries, resource
inheritance page-tree walk, Form XObject and Type 3 resource isolation,
ResourceStack design, EI disambiguation in binary data, lazy decompression
