Remove workspace dist source maps in the deps stages.

The old build stage removed source maps after the build. That cleanup was removed. container-image-trim.mjs now removes .map files only under the root node_modules. Both find passes prune dist, so every apps/*/dist/**/*.map and packages/*/dist/**/*.map file reaches the core, browser, and CLI images. This adds image size and can ship sourcesContent. The fix is to add one .map deletion that runs inside dist.

♻️ Proposed fix (repeat in each deps-* stage)

Review comment at @Dockerfile around lines 24 - 29:
Add a `.map`-file deletion pass to each affected `deps-*` stage in the
Dockerfile, pruning `node_modules` while matching source maps under workspace
`dist` directories. Preserve the existing test-file cleanup and
dependency-directory listing.

Record the Linux/arm64 measurements for core and cli.

Issue #64 requires the lowered budgets to include their measurements. This comment records only an approximate arm64 delta for core and cli. Add their measured values. This is a documentation gap; it does not show that either image exceeds its size ceiling.
