[Bug][low-prio]: openviking-server doctor doesn't report ov.conf error

[xiaobin83]

Bug Description

Version: 0.3.22

I have

{
  "retrieval": {
    "top_k": 10,
    "threshold": 0.5
  }
}

in the config. when executing openviking-server, it says,

Unknown config field 'retrieval.top_k'
Unknown config field 'retrieval.threshold'

but when executing openviking-server doctor , it says,

OpenViking Doctor

  Config:        PASS  /Users/wangtingting/.openviking/ov.conf
  Python:        PASS  3.12.13 (>= 3.10 required)
  Native Engine: PASS  variant=native
  AGFS:          PASS  AGFS SDK 0.1.7
  Embedding:     PASS  volcengine/doubao-embedding-vision-250615
  VLM:           PASS  deepseek/deepseek-v4-flash
  Ollama:        PASS  not configured
  Disk:          PASS  6.6 GB free in /Users/xxxx/.openviking/data

  All checks passed.

I think configuration error should also be reported in doctor command.

Steps to Reproduce

1. Put

{
  "retrieval": {
    "top_k": 10,
    "threshold": 0.5
  }
}

in ov.conf

2. run openviking-server, see the output.
3. run openviking-server doctor, see the output.

Expected Behavior

1. openviking-server fails with

Unknown config field 'retrieval.top_k'
Unknown config field 'retrieval.threshold'

2. openviking-server doctor reports 'error in ov.conf'

Actual Behavior

1. openviking-server fails with

Unknown config field 'retrieval.top_k'
Unknown config field 'retrieval.threshold'

2. openviking-server doctor reports 'All checks passed.'
