What does this PR do?

PR #14828 introduced a typecheck -> ^build dependency in Turborepo. This PR reverts that change to restore the previous task graph behavior.

• Reverted task graph change
  • turbo.json tasks.typecheck is restored from:

    { "dependsOn": ["^build"] }

    back to:

    {}

• Scope
  • Single-file change (turbo.json), no functional changes outside task orchestration.

How did you verify your code works?

Confirmed the revert matches the inverse of #14828 and that turbo.json remains valid JSON after the edit.

If this is a UI change, please include a screenshot or recording.
