AI Summary

Enhances syntax parsing capabilities with new language support and updates the build infrastructure to use Ubuntu 22.04.

Key Highlights

Updated tree-sitter parsers for Erlang, F#, Gleam, Pascal, and Swift
Added support for Verilog and SystemVerilog
Stricter file detection for UTF-8 and recognition of more compression types as binary
Switched from MiMalloc to Jemalloc for allocation

Breaking Changes

Prebuilt binaries now require a newer glibc version to run due to Ubuntu 22.04 CI usage

New Features

Parser updates for multiple languages
File detection improvements
Build system updates (CI)
Allocation library switch

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.
