release: publish the MIT set before the GPL one

[pcarrier]

Follow-up to #157: the fix for the review comment about .publish-order was pushed to the branch after the merge commit was cut, so it never landed on main.

publish-npm-bin-packages walks .publish-order under set -e. Sorting all platform packages into one block puts @blit-sh/bin-gpl-* ahead of the @blit-sh/bin launcher, so a failure publishing any GPL package aborts the run before the MIT launcher — the thing everyone installs — goes out. That's the same class of breakage #157 was fixing.

Emit one block per flavor, MIT first:

@blit-sh/bin-darwin-arm64
@blit-sh/bin-darwin-x64
@blit-sh/bin-linux-arm64
@blit-sh/bin-linux-arm64-musl
@blit-sh/bin-linux-x64
@blit-sh/bin-linux-x64-musl
@blit-sh/bin
@blit-sh/bin-gpl-linux-arm64
@blit-sh/bin-gpl-linux-arm64-musl
@blit-sh/bin-gpl-linux-x64
@blit-sh/bin-gpl-linux-x64-musl
@blit-sh/bin-gpl

Verified against fixture tarballs for both the full set (above) and a MIT-only artifact dir (no GPL block, @blit-sh/bin last).

PR Summary

Re-applies a fix lost from #157: the launcher's optionalDependencies fix landed on main, but the matching .publish-order change was pushed after the merge commit was cut and never made it. publish-npm-bin-packages walks .publish-order line-by-line under set -euo pipefail, so the old order (GPL platform packages interleaved before the @blit-sh/bin line) meant any GPL publish failure could abort the run before the widely-installed MIT launcher shipped. This reorders the manifest so the entire MIT flavor goes out before any GPL package.

• bin/build-npm-bin-packages: emit .publish-order as mit_names → @blit-sh/bin → (if GPL present) gpl_names → @blit-sh/bin-gpl, instead of all platform packages interleaved followed by both launchers.
• Each launcher still publishes after its own platform dependencies, so install-time optionalDependency resolution is unchanged.
• No package contents or version change.
