Implementations

• Alien is currently the fastest mainstream signal library for JavaScript.
• Reactievly is another fast signal library for JavaScript but has been overshadowed by Alien.
• Dumbdumb is the simplest approach to signal propagation. It's using the core mechanisms of how most spreadsheet engines work.
• 🚀 is a combination of core ideas of zignals combined with explicit code gen

[!WARNING] Dumbdumb and 🚀 are the only ones thread safe! This is actually togglable in codegen but the numbers are good enough it's left on in the benchmarks as it's better in a real world sense. This is not about distributing the workload, more about access safety
