Added support for Verilog and SystemVerilog
Stricter UTF-8 file detection and binary recognition
CI moved to Ubuntu 22.04
Switched from MiMalloc to Jemalloc for allocation

Breaking Changes

Prebuilt Linux binaries now require glibc version 2.35 or newer due to Ubuntu 22.04 upgrade

New Features

Updated tree-sitter parsers
Added Verilog and SystemVerilog support
Enhanced file detection for binary types

Full Release Notes

Difftastic is a structural diff tool that understands syntax. See [the manual](https://difftastic.wilfred.me.uk/) to get started, and [the changelog](https://github.com/Wilfred/difftastic/blob/master/CHANGELOG.md) for historical changes.

### Parsing

Updated to the latest tree-sitter parser for Erlang, F#, Gleam, Pascal and Swift.

File detection is now stricter for UTF-8, and recognises more compression file types as binary (e.g. zstd or bzip2).

Added support for Verilog and SystemVerilog.

### Build

CI on GitHub now uses Ubuntu 22.04 for Linux builds (previously Ubuntu 20.04), so prebuilt binaries will require a newer glibc version to run.

### Internal

Difftastic has switched from MiMalloc to Jemalloc for allocation. This is modest performance regression (up to 20% longer runtime in testing). Jemalloc is currently easier to build (see issue #805) and has fewer pathological performance corner cases.
