[JS] ai.prompt('_FILENAME')

[tailot]

Describe the bug
The genkit framework raises an exception when I try to call a prompt file whose name starts with the '_' character.

To Reproduce
define a file among your prompts with the name _verify.prompt and run in your flow:

   const verifyPrompt = await ai.prompt('_verify');

Expected behavior
Normal execution of the program.

Software version:

• OS: macos 15.4.1 (24E263)
• Node: v22.15.0
• genkit: 1.8.0 and 1.9.0

Additional context
I tested it in both 1.8 and 1.9
