What happened?

Hey 👋

When trying to build with go1.26rc1 in

• go 1.26.0, go@1.25 1.25.7 (new formula) Homebrew/homebrew-core#258912

the build failed with runtime go1.26rc1 not found in compat.yaml, because no go1.26 entry in compat.yaml file yet.

From previous Go releases, eg

• go 1.25.0, go@1.24 1.24.6 (new formula) Homebrew/homebrew-core#226636

it was noted that even after

• the entry was added in 20257fa
• released in https://github.com/syncthing/syncthing/releases/tag/v1.30.0
• release v1.30.0 used in syncthing 1.30.0 Homebrew/homebrew-core#228723

...but the build with still failed with go release candidate (rc2) due to strict runtime matching. Can this be made less strict, matching the prefix (eg go1.25 or go1.26), but forgiving the sufix rc1 or rc2 and similar?
