A mistyped task setting such as `cache: { outputs: [...] }` failed with
"data did not match any variant of untagged enum UserTaskDefinition".
Deserialize `UserTaskDefinition` and `UserCacheConfig` by value type so
the error of the form the user wrote is shown instead.

Replace the hand-written `Visitor` impls for `UserTaskDefinition` and `UserCacheConfig` with `serde_untagged::UntaggedEnumVisitor`. Error messages are unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

There was a problem hiding this comment.
Thank you! I pushed to simplify a little bit with serde-untagged.

Motivation
A mistyped setting in a task, such as
cache: { outputs: ["dist/**"] }(the field isoutput), fails with an error that names neither the key nor what is accepted:UserTaskDefinitionandUserCacheConfigwere#[serde(untagged)], which discards each variant's own error. They now pick the variant from the value's type, so the real error comes through:Valid configs parse as before and
run-config.tsis unchanged. The error still doesn't name the task; that needs path tracking in the config loaders.The main report in the issue (a cache hit that doesn't restore files) is already fixed by #461.
