Summary

Removes the last ember-cli-babel 7 path through @embroider/util. Upstream won't release util again.

• ember-element-helper ^0.8.7, a v2 addon that no longer depends on @embroider/util. Same API.
• Node 20 required. The util fork's dependency tree doesn't install on Node 18 with yarn v1 (pkg-entry-points 1.1.2, mktemp 2.x). engines.node, the README and CI move to Node 20, and the pkg-entry-points 1.1.1 resolution is dropped.
• @embroider/util comes from Gaurav0/embroider-util#v1.13.5-scf.1. It's a fork of 1.13.5 whose only changes are in package.json: ember-cli-babel ^8.3.2, @embroider/macros >=1.19.7 <1.21.0, and Node >= 20.
  • The runtime files are byte-identical to 1.13.0–1.13.5, and it keeps the @embroider/util name. Embroider trusts ensure-safe-component by that name, so no templates change.
  • Unwrapping ensure-safe-component isn't an option for a v1 addon: Embroider would reject the 25 currying sites with "Unsafe dynamic component".
• @embroider/macros moves to >=1.19.7 <1.21.0.
  • 1.18.1 fixed the lazy importSync that util relies on.
  • 1.19.7 is the first release that allows ember-cli-babel 8.
  • 1.21.0 became a v2 addon, which we're not taking yet.
  • A ~1.20.7 resolution keeps the dummy app on the same macros version consumers get.
• New BsModal tests pass a curried (component "...") and a component class as @headerComponent and @bodyComponent.

+76/−11 lines, not counting yarn.lock.

Breaking changes (5.0.0 release notes)

• Requires Node 20.
• ember-bootstrap now has a git dependency, so installs fetch the util fork from GitHub. The fork moves to SeeClickFix/embroider-util before 5.0.0 is tagged.
• Apps need @embroider/macros >= 1.18.1. Apps whose lockfile is older should run yarn upgrade @embroider/macros.

Stack

Part of the SCF-2416 work (ember-bootstrap 5.0.0), split from scf-2416-rework for easier review. This is part 4 of 9. Stacked on Part 3: its base is gaurav/chore/SCF-2416-part-3-build-deps, so the diff only shows this part. Merge in order.

Review notes

The fork is the main decision to review. The fork commit's message explains why it's needed and what was ruled out.

Testing

Run on this branch with Node 20.19.6: yarn install --frozen-lockfile passes, yarn lint reports 0 errors (the same 150 warnings as scf_master), and ember test (Ember 4.8, the default) has 538 passed, 9 skipped and 0 failed. +4 BsModal tests. CI covers the ember-try matrix.
