chore: migrate package manager from npm/pnpm/bun to aube (#455)
## Summary

Switches the project's package-manager surface from a mix of `npm` /
`pnpm` / `bun` (different commands in different files) to a single tool:
[aube](https://aube.en.dev), en.dev's pnpm-compat package manager
(native Rust, fast, drops cleanly into pnpm/npm-compatible workflows).

| | Before | After |
|---|---|---|
| Workflows install step | `npm ci` | `aube ci` |
| Workflows run scripts | `npm run X` | `aubr X` (`aubr` is the `aube
run` shorthand) |
| `mise.toml` tasks | mixed `npm run` / `bun run` | `aubr X` |
| Lockfile | `package-lock.json` | `package-lock.json` (unchanged — aube
reads it directly) |

The `aubr` binary ships alongside `aube` in the same install — it's the
script-runner shorthand (`aubr <script>` ≡ `aube run <script>`). Saves a
word in every workflow / mise.toml line.

## What didn't change

- **`package-lock.json`** stays as the canonical lockfile. aube reads it
directly; no `aube-lock.yaml` is generated. Running `npm install` still
works for any dev who hasn't switched to aube yet.
- **`package.json` scripts** still use `npm run X` for nested
invocations (e.g. `"all": "npm run format:write && …"`). The literal
`npm` works for both callers — aube's shell exec finds `npm` in PATH,
the inner invocation re-runs the same package.json script. Keeping these
PM-agnostic avoids a forced cutover for downstream contributors.
- **`dist/`** is byte-identical after `aubr all` — parity with the
npm-built bundle verified locally.

## New project files

- **`.npmrc`** — single line: `node-linker=hoisted`. Forces a flat,
npm-style `node_modules` layout instead of aube's default
symlink/virtual-store. Required because `rollup --configPlugin
@rollup/plugin-typescript` resolves the plugin from cwd's node_modules,
and the isolated layout puts rollup under `node_modules/.aube/...` where
standard module resolution can't reach back to the project root for the
plugin. npm reads `.npmrc` but ignores `node-linker` (npm always
installs flat), so the file is safe for both PMs.
- **`pnpm-workspace.yaml`** — generated by aube 1.4 to record
build-script approvals (`unrs-resolver: false`). Project-level config;
commits like a `package.json` companion.

Pinned `aube = '1.4'` in `mise.toml`'s tools so `mise install`
provisions the right binary locally.

## Why aube

Single tool replacing three. Less context-switching for contributors,
fewer places to run `npm audit` / `bun upgrade` / `pnpm dedupe`. aube's
cold-cache install for this repo's deps is ~3s vs `npm ci` at ~10s.

## Test plan

- [x] `aube install` from clean — succeeds, all 441 packages link
cleanly
- [x] `aubr all` (format + lint + package) — succeeds, `dist/`
byte-identical to checked-in version
- [x] `aubr format:check` — clean
- [x] `aubr lint` — clean
- [x] `aubr package` — produces `dist/index.js`, `dist/index.js.map`,
`dist/licenses.txt` matching what's checked in
- [ ] Workflows: `Continuous Integration` / `autofix.ci` / `Check dist/`
/ `test` all pass on this PR

> [!NOTE]
> **Medium Risk**
> Mostly CI/build-system plumbing; risk is workflow or packaging
breakage (dependency install layout, rollup config) that could prevent
`dist/` from rebuilding or CI from running, but it doesn’t change
runtime action logic.
> 
> **Overview**
> Switches GitHub Actions workflows to install tooling via
`jdx/mise-action` and run installs/scripts with `aube`/`aubr` instead of
`actions/setup-node` + `npm ci`/`npm run`.
> 
> Pins `aube` (`1.4`) in `mise.toml`, updates `mise` tasks and developer
docs (`CLAUDE.md`) to use `aube`/`aubr`, and adds `.npmrc`
(`node-linker=hoisted`) plus a `.gitignore` entry to avoid committing
`aube`’s generated `pnpm-workspace.yaml`.
> 
> Adjusts the packaging script to use `rollup.config.mjs` (replacing the
previous TS config invocation).

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a GitHub Action that installs and configures mise, a polyglot runtime manager. The action is written in TypeScript and published to the GitHub Actions marketplace.

Development Commands

This project uses aube as its package manager (en.dev's pnpm-compat PM, native Rust). It reads package-lock.json directly — no separate aube-lock.yaml. mise install will install the pinned aube version automatically; you can also use npm if you prefer (the .npmrc's node-linker=hoisted pin is aube-specific and ignored by npm).

# Install dependencies
aube install

# Build, format, lint, and package
aubr all

# Individual commands
aubr format:write  # Format code with Prettier
aubr lint         # Run ESLint and format check
aubr package      # Bundle with rollup for distribution

# Testing
aubr all          # Run full build pipeline
./scripts/test.sh     # Integration test script

Architecture

The action follows GitHub's standard TypeScript action structure:

  1. Entry Point: src/index.ts - Main action logic that:

    • Downloads and installs mise binary
    • Manages caching through GitHub Actions cache
    • Configures environment variables (MISE_*, GITHUB_TOKEN)
    • Runs mise commands (install, reshim, etc.)
    • Exports mise environment variables to GITHUB_ENV
  2. Distribution: dist/index.js - Compiled and bundled output (must be committed)

  3. Action Definition: action.yml - Defines inputs, outputs, and metadata

Key Implementation Details

  • Cache Management: Uses content-addressable caching based on mise config files (.mise.toml, .tool-versions, etc.)
  • Binary Download: Supports downloading from GitHub releases or mise.jdx.dev
  • Platform Support: Handles Linux (glibc/musl), macOS, and Windows
  • Environment Setup: Automatically adds mise bin and shims directories to PATH
  • GitHub API: Uses GITHUB_TOKEN to avoid rate limits when installing GitHub-hosted tools

Important Notes

  • Always run aubr all before committing to ensure dist/ is updated
  • The dist/ folder must be committed as GitHub Actions runs the compiled code
  • Test changes using the action itself (uses: ./) in test workflows
