Add @cratis/eslint-plugin-arc

[woksin]

Added

• @cratis/eslint-plugin-arc: ESLint rules for projects that consume Cratis Arc, designed to compose on top of @cratis/eslint-config.
  • skip-generated-proxies (processor) — skips Arc-generated proxy files wholesale. They carry a // @generated by Cratis header (and a **DO NOT EDIT** banner), cannot be edited, and are regenerated by the build, so any lint finding on them is un-actionable. Keyed on the header because generated proxies sit intermixed with hand-written .ts under the same folders, with no path distinction. The pass-through preserves filenames (import resolution is unaffected) and keeps --fix working on hand-written files.
  • no-hooks-in-view-model (rule) — forbids React hook calls inside MVVM view models (classes named *ViewModel). A view model must be a plain, React-free class; inject Cratis abstractions instead of calling hooks. Only bare-identifier hook calls are flagged, so view-model methods that merely start with use are not false positives. The class suffix and hook pattern are configurable.

Notes

• Named per the ESLint scoped-plugin convention (@scope/eslint-plugin-*). The plugin namespace is @cratis/arc, so rule IDs read @cratis/arc/no-hooks-in-view-model.
• Ships as raw ESM (no build step), declares only eslint as a peer dependency, and exposes meta.version plus per-rule docs URLs. It owns these rules because Arc owns the proxy generator and @cratis/arc.react.mvvm.

⚠️ One-time first-publish bootstrap (before this releases cleanly)

This PR adds a brand-new npm package — @cratis/eslint-plugin-arc. The Publish workflow uses npm trusted publishing (OIDC) (it strips the auth token), which requires a trusted-publisher relationship that must already exist on the package. That can't be configured before the package exists, so the package's first publish over OIDC will fail.

One-time bootstrap (do before merge, or after — the companion resilience commit means an un-bootstrapped package no longer blocks the others):

• Initial token-based publish to create the package, authenticated to npm with publish rights to @cratis:

  cd Source/JavaScript/Arc.ESLint
  npm publish --access public

  (or run with a granular NODE_AUTH_TOKEN). publishConfig.access: public is already set.
• Configure the trusted publisher: npmjs.com → @cratis/eslint-plugin-arc → Settings → Trusted Publisher → repository Cratis/Arc, workflow .github/workflows/publish.yml.
• Verify the next Publish run publishes over OIDC with no token.

Heads-up — co-versioning: publish-version sets every workspace to the repo release version, so on the first automated release this package jumps to ~20.x (matching @cratis/arc), not 0.x/1.0.0. Starting it independently would need a release-pipeline change.

@einari — two one-time steps before merging this. This is 1 of 3 coordinated PRs: Fundamentals Cratis/Fundamentals#1072, Arc #2273, Components Cratis/Components#95.

1. Bootstrap @cratis/eslint-plugin-arc on npm (one-time)

The Publish workflow uses OIDC trusted publishing, which can't create a package that doesn't exist yet — so the first publish has to be done by hand. From a checkout of this branch, authenticated to npm with publish rights to @cratis:

cd Source/JavaScript/Arc.ESLint
npm publish --access public

Then on npmjs.com → @cratis/eslint-plugin-arc → Settings → Trusted Publisher: repository Cratis/Arc, workflow .github/workflows/publish.yml. (publishConfig.access: public is already set; the throwaway 0.0.0 gets superseded by the real version on the first automated release.)

2. Merge with the minor label (already applied)

Merging triggers the Publish workflow, which co-versions and releases every workspace over OIDC — including the now-bootstrapped package.

Order: bootstrap → merge for a fully-green first release. Merging before bootstrapping is safe too — the resilience commit means this new package failing to publish no longer blocks @cratis/arc or the other workspaces; it just won't publish until bootstrapped.

Versioning note: co-versioning makes this plugin debut at ~20.x (the repo version), not 1.0.0. Say the word if you want it versioned independently and we'll adjust the pipeline first.
