fix: replace go-touchid to support fallback when biometrics are not available

[noamcohen97]

Summary

Replace github.com/lox/go-touchid with github.com/noamcohen97/touchid-go to fix authentication failures
when Touch ID is unavailable (e.g. MacBook lid closed, biometrics not enrolled).

Issues in current library

The old library (lox/go-touchid) has several issues:

1. Hardcoded biometrics-only policy - It uses LAPolicyDeviceOwnerAuthenticationWithBiometrics,
   which requires biometric hardware to be available and enrolled. When Touch ID is unavailable (e.g. screenclosed, no biometric sensor), canEvaluatePolicy returns false and the library provides no fallback.
2. Hangs when biometrics are unavailable - When canEvaluatePolicy returns false, the code skips the
   evaluatePolicy call but still calls
   dispatch_semaphore_wait, which blocks forever since no one signals the semaphore.

The new library (noamcohen97/touchid-go) avoids all of the above - it properly manages LAContext lifecycle, returns early on canEvaluatePolicy failure, and lets the caller configure the LAPolicy.
This PR uses DeviceOwnerAuthentication to allow the system to fall back to the device passcode/password when biometrics are unavailable. Just like advised in the Apple documentation:

To let the system handle the fallback option by asking for the device passcode (in iOS or watchOS) or the user’s password (in macOS), use the LAPolicy.deviceOwnerAuthentication policy instead.

Thanks, are you maintaining that library @noamcohen97? Looks like it's not a fork, but improved implementation.

[noamcohen97]

Yes! I wrote it because I couldn't find any library that is context-aware, supports multiple policies, and parses error codes.

Thanks for reviewing @mbevc1 !

Hey, @noamcohen97 have you tried compiling for Darwin Arm? Seems Homebrew is hitting this one: https://github.com/Homebrew/homebrew-core/actions/runs/22149824417/job/64038209199?pr=268190#step:3:127

In this case, it's the older macOS version that is causing the compilation failure. I just released v0.3.0 that should address this compatibility issue.
Sorry about that
I created #70 to address it, I'm not sure how long it will take for dependabot to catch up

[mbevc1]

Thanks, merging now!

[noamcohen97]

I will bump Homebrew formula as son as fixed version of aws-vault will be released.
Again - sorry about that

[mbevc1]

No worries @noamcohen97 and thanks for a quick response. homebrew should be picking it up shortly

[noamcohen97]

I figured that the patch must be removed

[mbevc1]

Yes, we should remove that now

[noamcohen97]

Done!
