chore: migrate package manager from npm/pnpm/bun to aube
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).

## What changed

- **Workflows** (`.github/workflows/*.yml`): every `npm ci` →
  `aube ci`; every `npm run X` → `aube run X`. The
  `actions/setup-node@…` step still pins Node, then a new
  `jdx/mise-action@v4` step with `install_args: aube` installs
  aube. The `cache: npm` directive on `setup-node` is dropped
  (aube uses its own store under `~/.cache/aube`; reusing the
  npm cache wouldn't help).
- **`mise.toml`**: every task that ran `npm run X` or
  `bun run X` now runs `aube run X`. Added `aube = '1.3'` to
  the tool list so `mise install` provisions it locally.
- **`CLAUDE.md`**: development command snippets updated to
  `aube install` / `aube run all` etc.

## What didn't change

- **`package-lock.json`** stays as the canonical lockfile —
  aube reads it directly, no separate `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` in those works for both npm callers and aube
  callers (aube exec'd shell finds `npm` in PATH; the inner
  invocation reads the same package.json scripts). Avoiding
  the rewrite to `aube run X` here keeps the scripts
  PM-agnostic.
- **`dist/`** is byte-identical after `aube run all` —
  parity with npm-built dist verified locally before this
  commit.

## `.npmrc`

Adds a single line: `node-linker=hoisted`. This is the
pnpm/aube key that forces a flat, npm-style `node_modules`
layout instead of the default symlink/virtual-store layout.
Required because `rollup --configPlugin @rollup/plugin-typescript`
needs to resolve the plugin from cwd's node_modules; 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` too but
ignores `node-linker` (npm always installs flat), so the
file is safe for both PMs.

## Why aube

Single tool replacing three: less context-switching for
contributors, fewer places to run `npm audit` / `bun
upgrade` / `pnpm dedupe`, and aube's resolver is faster
than npm's (the `aube install` cold-cache run takes
~3s vs `npm ci` at ~10s for this repo's deps).

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
