PF-3329: Migrate to pnpm@10, Node 24, GitHub Packages

[genisd]

Scope

Migrate this package to pnpm@10.33.4, Node 24, and GitHub-Packages-only publishing on top of util.workflowJavascriptPackage() from lib-jsonnet. Also performs a publish-hygiene pass adding a files allowlist.

lib-jsonnet bootstrap

This repo was bootstrapped to lib-jsonnet as part of this PR (no .github/jsonnet/ existed before). Helpers were extracted from https://files.gynzy.net/lib-jsonnet/v1/jsonnet-pr-257.tar.gz.

Depends on lib-jsonnet#257 (adds packageManager='pnpm' to workflowJavascriptPackage). Follow-up once adopted-ember-addons#257 merges to prod: re-run sh .github/jsonnet/pull-upstream-and-rebuild.sh without PR_NUMBER to repin helpers to prod and regenerate.

Discovery

Field	Value
Default branch	main
Visibility	PUBLIC → isPublicFork=true
Version bump	0.10.0 → 0.10.1
Test cmd	npm-run-all lint:* test:* (lint:js, test:ember, test:ember-compatibility)
Build cmd	ember build --environment=production
Lint cmd	npm-run-all --parallel lint:*
Service deps	none

Workflow generation

• repositories=['github'] — GitHub Packages only (hard requirement: no npm.gynzy.net, no setGynzyNpmToken). Verified: generated YAML contains zero references to either.
• isPublicFork=true (visibility PUBLIC).
• buildSteps=[] — the legacy ci/publish.sh published yarn publish directly without a build step; preserving original behavior. Also: ember build does not run on Node 24 with the pinned Ember 3.27 toolchain.
• testJob runs pnpm run lint (eslint) only. test:ember and test:ember-compatibility need a browser environment that the node:24 container does not provide; Travis previously used chrome: stable addon. Flagged below.

Legacy .github/workflows/publish-pr.yml and publish-tag.yml were deleted (superseded by helper-generated pr.yml and publish-prod.yml).

Publish hygiene

Baseline pnpm pack (before allowlist): 49 files / 49,727 B. Junk shipped: .github.jsonnet, all of .github/jsonnet/*, .github/workflows/*.yml, .claude/, .nvmrc, ci/npm.sh, ci/publish.sh, CHANGELOG.md, CONTRIBUTING.md.

CI bloat risk (generated workflows): pnpm config set store-dir .pnpm-store && pnpm install --frozen-lockfile runs before pnpm publish, which without an allowlist would balloon the published tarball with the pnpm store. The allowlist neutralises this.

Applied:

• files: ["addon", "app", "config/environment.js", "index.js"]
• .npmignore deleted (allowlist makes it redundant; the only residual noise inside allowlisted paths is two 0-byte .gitkeep files — harmless).

After: 14 files / 5,771 B (–88% size, –71% files).

Local verification

• pnpm install — clean.
• pnpm run lint:js — passes.
• pnpm run build — fails on Node 24 (pre-existing Ember 3.27 / Node-24 incompatibility); not wired into CI testJob or publish-prod (buildSteps=[]).
• pnpm run test — not run (browser-dependent ember tests; see Open Questions).

Preserved

• .travis.yml left as-is (not a GH Actions workflow). Travis is the historical home of ember-try matrix tests.
• ci/npm.sh, ci/publish.sh left as-is (orphaned scripts, no longer referenced by any workflow). Can be removed in a follow-up.

Open Questions

• Tag-publish trigger: legacy publish-tag.yml fired on push: tags: '*'. The new helper publishes on push to main. Confirm whether tag-based releases are still desired; if so, additional jsonnet is needed.
• Ember test execution: test:ember and test:ember-compatibility need a browser. They previously ran on Travis with Chrome installed. Wiring them in GH Actions requires a service container or runner-installed browser — out of scope for this migration. They are NOT run in CI by this PR.
• ci/npm.sh / ci/publish.sh orphan removal: not part of this PR per minimum-change rule; suggest deleting in a follow-up.
