Rework release config diff to compare version against active version

[isaacroldan]

Part 5 of 8 — splitting #8040.

WHY are these changes introduced?

Both release and the new deploy classification need to diff app configuration between two module sets. This introduces that shared primitive and adopts it in release, independently of the deploy change.

WHAT is this pull request doing?

• Adds buildConfigExtensionIdentifiersBreakdown (a plain local-vs-remote field diff using the order-insensitive array comparison from Add order-insensitive deep object comparison to cli-kit #8044) and configExtensionsIdentifiersReleaseBreakdown.
• Switches release to them: the config breakdown now compares the version being released against the app's active version instead of re-fetching remote configuration.

Only affects the release command; the shared helper is reused by #8055.

⚠️ Changes how the release config diff is computed/displayed — consider a patch changeset.

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.
