Include bin hash in cache key

[bhperry]

Add sha256 hash of the micromamba binary to the cache key so broken environments created from previous versions won't be restored for a new version.

Closes #91

Could you also compile the action and bump its version in package.json?

@pavelzw minor bump for this?

[pavelzw]

Sure 👍🏻

Is test.sh outdated? Tried to run it, but no index.js in dist

[pavelzw]

Yes seems like it 🤔 I nowadays just run the tests from GitHub ci

Error: src/cache.ts(43,22): error TS2339: Property 'readBinaryFile' does not exist on type 'typeof import("fs/promises")'.

[bhperry]

hmm looked that one up somewhere, guess I was looking at the wrong fs package

[bhperry]

seems like regular readFile with no encoding should do the trick

[pavelzw]

The ci failures look unrelated. I'll take a look at them later

[pavelzw]

the remaining failing ci is tracked in #230

FWIW, this doesn't work as expected because a promise is interpolated into the cache key string rather than the value the promise resolves to, e.g. I see cache keys like:

2025-09-16-linux-64-augur-args-30d39f4-root-dcc80ee-bin-[object Promise]

The issue is this bit of code added by 59b1132

setup-micromamba/src/cache.ts

Lines 43 to 45 in 7f29b8b

	const binHash = fs.readFile(options.micromambaBinPath).then(sha256)
	const key = `${prefix}${arch}${envName}${createArgs}${rootPrefix}-bin-${binHash}`

because binHash is a promise.
