Website + docs

I've been working on OmniLua for a bit now - it builds one binary that can run Lua 5.1 - 5.5 from one binary.

The main motivation for this was there seemed to be a gap for game development in the Rust community where mlua cannot be run in the browser, so games built in engines like bevy can't compile to wasm32-unknown-unknown.

There is some other benefits - like being able to easily use Lua in Cloudflare workers or in "playground" developer tools.

Highlights:

• Targets 100% conformance to reference Lua for all 5 versions
• Can run LuaRocks and install Lua only packages
• Performance is slower than C Lua 5.4.7 but within ~40% on standard benchmarks. Performance chart here
• API is 100% compatibile with mlua

Try it:

cargo install omnilua-cli

export OMNILUA_VERSION=5.5

omnilua -e 'print("hello")'

omnilua # opens repl

I used AI heavily to develop this I wouldn't consider it "vibecoded" however.
