Preserve devtools runtime dependency in ankh

[artiphishle]

Summary

• keep @ankhorage/devtools in dependencies when synchronizing @ankhorage/ankh
• continue using devDependencies for normal consumer repositories
• remove duplicate/misplaced devtools entries from the opposite dependency section
• make package status detect incorrect dependency placement for @ankhorage/ankh
• document the runtime-provider exception in the Paradox @readme source comment
• add regression coverage for synchronization and drift detection
• add a patch changeset

Why

@ankhorage/ankh loads @ankhorage/devtools as a bundled core provider at runtime. The generic package sync contract previously moved devtools into devDependencies, which would make aggregate ankh devtools sync unsafe to run in the ankh repository itself.

After this release, aggregate ankh devtools sync can be used in @ankhorage/ankh as well as normal consumer repositories without changing the required runtime dependency placement.
