What's new?

This release is a modest attempt to follow a regular release cycle for glaucus.

A summary of changes that took place: - radula was rewritten in Nim (previous version was in Rust), reasons for this include: - code is reasonably more readable (more so than the Rust version) - much less LOC even with more features added (compared to the Rust version) - code is written in a reasonable amount of time (much less than Rust version, again the rewrite itself took about a month, but the speed at which newer features were added is like 4 - 8 times faster than in Rust, probably because I am not proficient in Rust even after a year of using it...) - uses less system resources (1/3 of what the Rust version uses) - much smaller executable size (200 to 300 KB) (compared to the Rust version 3 MB) - can be built using glaucus's existing toolchain because Nim transpiles to C; thus, making use of the optimized toolchain glaucus uses (unlike Rust which is very hard to bootstrap, and does not work all that great with shared musl...) - slightly faster (parsing cerata is around 6 - 20% faster overall) (this is probably because I am not proficient with Rust even after a year of using it, but then again I've only been writing in Nim for a month...) - glaucus's toolchain now uses mold by default, and all executables (with the exception of the Linux kernel) are being linked with it - glaucus now uses yash as the default shell for interactive use instead of oksh for the following reasons: - more strict POSIX compliance compared to oksh - much more user friendly compared to oksh - about 50% the size of bash and only slightly bigger (10 - 20%) than oksh - about 30 - 40% faster than bash and has identical performance to oksh and loksh - multiline support, which is not available in oksh - glaucus now uses OpenBSD M4 as the default M4 implementation - glaucus now uses BLAKE3 as the default hashing algorithm instead of SHA-512 - Update default ASCII art - Updated cerata

This release is more stable compared to previous releases but it still is not production ready.
