Correct Turbo build dependency graph for test-web

[joshuasilva414]

What to build

Make the Turbo configuration, package dependency declarations, and test-web CI build path accurately represent the build-time dependencies required by the HackKit runtime. Correct any mismatch discovered during the investigation and provide a repeatable validation path for contributors and CI.

Acceptance criteria

• The test-web build runs after every workspace package whose built output it transitively requires.
• CI validates the same dependency graph used by local development instead of relying on an incomplete manually maintained package list.
• Package declarations and Turbo task dependencies correctly encode required build ordering.
• A documented command or automated check verifies the dependency ordering and successful test-web build.
