[Bug] findUnknownConfigKeys fails to validate deeply nested array objects

[akramcodez]

Description

The collectUnknownKeys recursively checks shape but explicitly skips deeply nested array objects or Zod Unions. Any typo inside an array-of-objects in config.json won't be caught or surfaced to the user, leading to confusing ignored inputs.

Environment

• macOS version: macOS 14.0
• Apple Silicon: M2
• Node version: v22.0.0
• Python version: 3.12
• Nanotune version: 1.7.0

Steps to Reproduce

1. Add a typo to a deeply nested array object in config.json.
2. Run nanotune status.

Expected Behavior

A warning is surfaced to the user about an unknown config key.

Actual Behavior

The typo is silently ignored.

• I can reproduce this issue consistently
• This issue occurs with the latest version of nanotune
