Added typed config struct for unmapped glyph names configuration: - unmapped_glyph_names: Vec<String> - list of glyph names to skip - description: Option<String> - optional documentation - version: Option<String> - format version identifier The struct represents the JSON structure from build/unmapped-glyph-names.json and is ready for parsing implementation in follow-up beads. Closes bf-3vo80. Verification: notes/bf-3vo80.md

//! Fuzz target for the PDF stream decoder.
|
|
//!
|
|
//! This target tests INV-8 (no panic at public boundary) for the stream decoder.
|
|
//! Any panic indicates a stream decoder bug that must be fixed.
|
|
//!
|
|
//! This also tests EC-10 (decompression bomb) - the 512 MB limit must hold
|
|
//! under random predictor inputs.
