registry: make aube more resilient (cargo:aube)

[bgeron]

Aube isn't mise-installable in docker on mac (linux arm). This fixes that.

mise use cargo:aube does fail on arm mac native, because there seems to be an issue with the binstall binaries for aube:

> mise use -g cargo:aube
error: rustup could not choose a version of cargo to run, because one wasn't specified explicitly, and no default is configured.
help: run 'rustup default stable' to download the latest stable release of Rust and set it as your default toolchain.

cargo:aube@1.15.0            status: 1

However, presumably either the github download works, or mise will completely fall back to compiling from source. So I think this makes aube mise-installable in all cases.

Code Review

This pull request updates the registry configuration for 'aube' by adding 'cargo:aube' to the list of supported backends. There are no review comments, so I have no additional feedback to provide.

Greptile Summary

Adds cargo:aube as a fallback backend in registry/aube.toml to work around a broken binstall archive that is missing the aubr binary on arm linux (including Docker on Apple Silicon). The github:endevco/aube entry stays as the primary backend; cargo:aube is tried when the github download fails, so mise will compile from source rather than hard-error.

• Follows the same two-backend ["github:…", "cargo:…"] pattern already used for tools like atuin.
• No logic changes — purely a registry config update.

Confidence Score: 5/5

Single-line registry config change that adds a well-established fallback pattern; no logic is touched.

The change is a one-line addition to a TOML registry file, mirrors an existing pattern used throughout the repo, and directly addresses a documented installation failure on arm linux.

No files require special attention.

Important Files Changed

Filename	Overview
registry/aube.toml	Adds cargo:aube as a second fallback backend alongside the existing github:endevco/aube entry, following the same multi-backend pattern used by other tools like atuin.

No idea why CI is failing. It seems to be a generic issue with CI, not related to my registry change.
