Add a TinyGo WebAssembly guest example for Numax

[GianIac]

If you'd like to help with Numax, this is a great place to start, thank you so much for taking a look !

Add a minimal TinyGo guest example that runs inside Numax.

Why

Go matters to a lot of developers, but TinyGo is a more realistic first step than promising full Go support right away.
This issue helps validate a practical path.

Scope

Create an example that:

• is written in TinyGo
• compiles to .wasm
• exports run
• imports one or more nx host functions
• demonstrates logging or simple key/value access

Done when

• a TinyGo example exists in examples/
• build and run steps are documented
• the example works with nx run
• limitations are documented honestly

Notes

Please keep this scoped to TinyGo, not “full Go support”.

If something feels awkward or incomplete, that's totally fine, documenting the rough edges is part of the value here too.

Thanks again for considering contributing to Numax.

I can take this. The implementation seems similar to the other Guest examples, so i think it should be straightforward.

Just need to analyze how TinyGo handles imported WASM functions

TY !
