Subject: [PATCH] Conditionally import legacy-inspector-support per
 ember-source version
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The min-supported try-scenario was failing with:

    [vite]: Rollup failed to resolve import "@ember/enumerable/mutable"
    from ".../@embroider/legacy-inspector-support/src/modules-4-12.js"

`@embroider/legacy-inspector-support` ships three entry points sharded by
ember-source range:
  - ember-source-3.28  → Ember < 4.8   (uses legacy mutable-enumerable path)
  - ember-source-4.8   → Ember 4.8–4.11 (adds @ember/enumerable/mutable)
  - ember-source-4.12  → Ember >= 4.12 (also adds @ember/owner)

test-app/app/app.js was hard-coded to the 4.12 entry, so the min-supported
scenario (ember-source ~4.2.0) pulled in modules-4-12.js, which imports
`@ember/enumerable/mutable` — a module that doesn't exist in Ember 4.2.

Use macroCondition + dependencySatisfies + importSync from @embroider/macros
to pick the right entry at build time based on the installed ember-source.
The macros compile the untaken branches away, so each try scenario only
pulls in the import graph it can actually resolve.
