Regression on github backend using tool_alias and platforms asset_pattern

[jylenhof]

With this .mise.toml file :

[tool_alias]
guest-init = "github:jingkaihe/matchlock"

[tools."github:jingkaihe/matchlock"]
version = "latest"
platforms.linux-x64 = { asset_pattern = "matchlock-linux-amd64" }
platforms.macos-arm64 = { asset_pattern = "matchlock-darwin-arm64" }

[tools.guest-init]
version = "0.2.8"
platforms.linux-x64 = { asset_pattern = "guest-init-linux-amd64" }
platforms.macos-arm64 = { asset_pattern = "guest-init-darwin-arm64" }

With version <= 2026.2.9 I have this

jylenhof@pcportablejyl:~/github/mise-en-place-tips/tips_001$ matchlock
Matchlock is a lightweight micro-VM sandbox for running llm agent
securely with network interception and secret protection.

and

jylenhof@pcportablejyl:~/github/mise-en-place-tips/tips_001$ guest-init
FATAL: missing matchlock.dns
jylenhof@pcportablejyl:~/github/mise-en-place-tips/tips_001$

Using mise >= 2026.2.10 :

jylenhof@pcportablejyl:~/github/mise-en-place-tips/tips_001$ matchlock
Matchlock is a lightweight micro-VM sandbox for running llm agent
securely with network interception and secret protection.

jylenhof@pcportablejyl:~/github/mise-en-place-tips/tips_001$ guest-init
guest-init : commande introuvable
jylenhof@pcportablejyl:~/github/mise-en-place-tips/tips_001$

This is because on guest-init, this is not the right binary in the mise repo :

jylenhof@pcportablejyl:~/github/mise-en-place-tips/tips_001$ ls -la ~/.local/share/mise/installs/guest-init/0.2.8/
total 14336
drwxrwxr-x 2 jylenhof jylenhof        0  2 avril 15:34 .
drwxrwxr-x 3 jylenhof jylenhof        0  2 avril 15:34 ..
-rwx--x--x 1 jylenhof jylenhof 13689016  2 avril 15:34 matchlock
jylenhof@pcportablejyl:~/github/mise-en-place-tips/tips_001$

We should have guest-init here, as specified in the asset_pattern lookup
