state: save all the build packages as global
Metadata
Current evaluation
Merged in canonical/snapcraft#1340 (51401fc07), recording build packages globally at install time instead of capturing their versions per part.
Resolution: closed resolved
Reason: PR #1340 was merged and landed as commit 51401fc07. It records all installed build packages and versions globally before individual parts are pulled, replacing per-part dependency-cache capture.

Issue body
We install all the build packages before pulling the individual parts.
Before this branch, we first installed all the build packages, then pulled each individual part, and then the individual parts saved the versions of packages installed inspecting the dependency chain in the cache.
With this change, we save all the build packages and their versions when they are installed. So this changes a few things:
* If a build package is already installed, it won't be saved as an asset. So in the end, the recorded annotated snapcraft.yaml will be accurate only in cleanbuild, and requires that we also record the image used during cleanbuild.
* The recorded annotated snapcraft.yaml will be slightly different than the original, with all the build packages for all the parts as global packages. As we install all the build packages before any part anyways, this is equivalent.

| qwen/qwen3.6-35b-a3b | — | — | Merged. Saves all build packages globally upon installation instead of per-part. Simplifies state tracking, requires cleanbuild image recording, and produces a functionally equivalent annotated snapcraft.yaml. Approved and passed CI. | |
| qwen3.6-35b-a3b-mtp-q6 | — | — | Merged. Changes snapcraft to save all build packages as global dependencies during installation, aligning recorded state with actual resolution. The update passes CI and standardizes how build assets are tracked across parts. |
