{} `{}` already exists in package.toml

Error message

{} `{}` already exists in package.toml

What it means

Duplicate-dependency guard in `Package::add`: after parsing the new `use` string, an identical plugin or flavor entry already exists in package.toml, so adding it again is rejected to avoid duplicates. The faulting input is the `r#use` string being added.

Solutions

1. Skip adding the dependency — it is already managed.
2. Update the existing entry instead of adding a new one.
3. Remove the duplicate with `ya pkg delete` first if you truly want to re-add it.
