Puts github:nubjs/nub first in the nub registry entry for 0.9.5 and later, keeps npm:@nubjs/nub for the versions before it, and lists nubr as a third bin.

From nub 0.9.5 the release archives carry bin/nubx and bin/nubr themselves: relative symlinks to bin/nub in the tarballs, a small stub executable under each name in the Windows zips (nubjs/nub#956). A plain extraction is a complete install, so the GitHub backend can serve it. Earlier archives shipped only bin/nub, which is what kept the entry on the npm package and its Node launcher (#13191); min_version routes those versions to npm as before.

Verified on macOS arm64 with mise 2026.9.14, a clean MISE_DATA_DIR, and MISE_MINIMUM_RELEASE_AGE=0 because 0.9.5 is younger than a day:

$ mise ls-remote github:nubjs/nub | tail -3
0.9.2
0.9.3
0.9.5
$ mise install github:nubjs/nub@0.9.5
mise ✓ github:nubjs/nub@0.9.5  5.0s  nub-darwin-arm64.tar.gz
$ ls -l $MISE_DATA_DIR/installs/github-nubjs-nub/0.9.5/bin
-rwxr-xr-x  nub
-rwxr-xr-x  nub-launcher-darwin-arm64
lrwxr-xr-x  nubr -> nub
lrwxr-xr-x  nubx -> nub
$ mise x github:nubjs/nub@0.9.5 -- nubr --version
0.9.5
$ mise x github:nubjs/nub@0.9.5 -- nubx --help | head -1
Run a tool from `node_modules/.bin`, fetching it on a local miss (`npx`/`pnpm

The release publishes no artifact attestations, so there is no attestations_since. registry/nubr.toml stays on npm:@nubjs/runner, the Node-only runner package.

bins is one list per tool, not per backend. nubr exists in the npm package from 0.9.3, so only a pin at 0.9.2 or older gets a nubr shim with nothing behind it, the same as any tool that gained a bin between releases.

Summary by CodeRabbit

• New Features
  • Added support for the Nub backend, with a minimum required version of 0.9.5.
  • The nubr executable is now recognized alongside nub and nubx, allowing the registered backend to work with setups that use any of these Nub command-line tools. This expands the available Nub executable options without changing support for the existing binaries.

Confidence Score: 5/5

[Medium risk] Updates package registry configuration for nub tool.

The PR appears safe to merge.

Summary

The PR routes nub 0.9.5 and later through the GitHub backend, retains npm for earlier versions, and lists nubr as a bin.

• The only change since the previous review adds a trailing newline to registry/nub.toml; it does not change the registry configuration.

Do not expose nubr to pre-0.9.5 npm installs.

The top-level bins list is not version-filtered. Normal shim generation ignores missing files, but lazy requests use this list to create bootstrap shims and select providers. If a pre-0.9.5 npm archive lacks nubr, invoking its bootstrap shim installs the package and then fails to resolve nubr.

Make the bin metadata version-aware, or exclude nubr from lazy/provider resolution for npm-backed versions below 0.9.5.

@jdx, understood. The nubr metadata limitation remains, but I won’t ask for a change in this PR.
