migrate off libsodium

[dynst]

This removes a WebAssembly dependency and a huge chunk of bundle size https://bundlephobia.com/package/@cosmjs/stargate@0.34.0

(The other, even more huge chunk is cosmos/cosmjs-types#98)

Closes #584
Closes #907
Closes #964
Closes #1031
Closes #1478
Closes #1585

Related: #1479 #1796

Technically, now that there's no longer a quirky requirement to await sodium.ready at the start of every function, asynchronous methods could be made synchronous now after this PR.

Considered but rejected a faster alternative to @noble/hashes Argon2id At least as long as Node 20 is supported, looks like hash-wasm is needed https://bundlephobia.com/package/hash-wasm@4.12.0

But hopefully Argon2 just gets standardized in Web Crypto someday and then implemented by Node.js. https://twiss.github.io/webcrypto-modern-algos/#argon2

This conflicts with #1720 but let's get that one merged first.

This seems like really low-hanging fruit for a massive reduction in bundle size, is it not gonna make it into 0.35?

[webmaster128]

Looks straight forward at first glance. However, I would be very surprised if the pure-JS implementation of Argon2 is as fast as the WebAssembly one. So this PR has the potential to hit existing users hard. Which then leads to the questions: who uses CosmJS pro private key encryption at all? Should we remove that functionality alltogether?

[dynst]

I thought if it was going to be removed it already would've been.

Releasing a slower version could make for a good scream test. Maybe mark all the types with @deprecated for one release to see if anyone complains.

https://www.typescriptlang.org/docs/handbook/jsdoc-supported-types.html#deprecated

Or just switch to hash-wasm instead of libsodium or noble cryptography for a fast but much smaller Argon2id implementation.

[webmaster128]

Releasing a slower version could make for a good scream test.

Agreed. I would like to release a 0.36.0 tomorrow with ONLY this change in it. Then users can go back to 0.35.0 without a problem.

Could you update this PR to latest main?

[webmaster128]

Nice!

	/**
	* A KDF configuration that is not very strong but can be used on the main thread.
	* It takes about 1 second in Node.js 16.0.0 and should have similar runtimes in other modern Wasm hosts.

	params: {
	outputLength: 32,
	opsLimit: 24,
	memLimitKib: 12 * 1024,
	},
	};

The basic parameters run so slowly the unit tests fail to finish in 15s. Or 60s. At least when running on Node.js 20.

But 22 seems to have new optimizations. The result for Node 22 says:

https://github.com/cosmos/cosmjs/actions/runs/16947888017/job/48033364449

[@cosmjs/amino]:     8.3 deserialize
[@cosmjs/amino]:       ✓ can restore (10 secs)
[@cosmjs/amino]:       ✓ can restore multiple accounts (10 secs)

So just to keep CI happy - until Node.js 20 is dropped - maybe hash-wasm is necessary for now. It makes the unit test finish in less than a second.

The absolutely huge performance improvement for this low-level math code in 22 might be related to https://v8.dev/blog/maglev

If you merge this, just make sure and do a branch-merge and not a squashed commit, so it's easy to revert the last few commits separately later.

💅 we can use sleep from @cosmjs/utils which does exactly that but is a bit more readable
