Release Notes - gref v2.1.0

Version 2.1.0 (March 21, 2026)

Whole-buffer Regex Matching: Implementation of bytes::Regex to leverage SIMD, Teddy, and Aho-Corasick optimizations on full file buffers.
SIMD Literal Pre-filtering: Integration of memchr::memmem::Finder (shared via Arc).
Line-Boundary Detection: SIMD-accelerated detection via memchr/memrchr for incremental line counting.
Pipelined Execution: Concurrent walk+search architecture where workers process files as discovered.
Dependencies: Added memchr (explicitly managed).

Ignore Logic: Added gitignore.rs for .gitignore, .ignore, and .grefignore parsing with hierarchical rule merging and glob-to-regex conversion.
CLI Flags: Added --hidden and --no-ignore.
Windows Support: Hidden file detection via FILE_ATTRIBUTE_HIDDEN.
Zero-copy Path Filtering: Utilizes OsStr checks prior to entry.path() allocation.
Deferred Binary Detection: Extension-based lookup and SIMD null-byte scanning on loaded buffers.
Refactoring: Split file detection into classify_by_extension() and is_binary_content().

Scroll Logic: topline management moved exclusively to ui.rs to resolve scroll loops.
Rendering:
- Lines truncated to screen_width - 1 to prevent auto-wrap.
- Tab-to-space expansion prior to truncation.
Navigation: Fixed horizontal scroll maximum offset calculation.
