Add support for bun catalogs

[PaulRBerg]

Problem

Bun recently added support for catalogs, a feature analogous to pnpm catalogs. However, ni does not currently support this feature for bun workspaces.

This is analogous to #274, which requests pnpm catalog support.

Solution

Add a --catalog flag for bun workspaces that:

1. Updates the bunfig.toml file to add the dependency under a catalog
2. References the cataloged version in package.json

Example - Named Catalog:

ni lodash --catalog prod

Should update the catalogs in package.json.

And reference in package.json:

{
  "dependencies": {
    "lodash": "catalog:prod"
  }
}

Example - Default Catalog:

ni lodash --catalog

Should use the default catalog in bunfig.toml.

Note

This feature was introduced in Bun v1.2.9.

nup

It would be helpful if the feature also worked for nup (updating packages) not just ni.

Btw it's not workspace.catalogs.prod instead bun uses package.json like other workspace configs (also it was added in bun v1.2.14).

see docs or below for some examples https://bun.sh/docs/pm/catalogs

// package.json
{
  "dependencies": {
    "react": "catalog:",
    "zod": "catalog:dev"
  },
  "workspaces": {
    "packages": ["packages/*"],
    "catalog": {
      "react": "^19.0.0"
    },
    "catalogs": {
      "dev": {
        "zod": "4.0.0-beta.1"
      }
    }
  }
}

// package.json
{
  "dependencies": {
    "react": "catalog:",
    "zod": "catalog:dev"
  },
  "workspaces": ["packages/*"],
  // they can be top level too
  "catalog": {
    "react": "^19.0.0"
  },
  "catalogs": {
    "dev": {
      "zod": "4.0.0-beta.1"
    }
  }
}
