fix: normalize search response for Docmost 0.25+ API change

Closes #1
Closes #8

Docmost changed the search API response format in v0.25.0:
- Before: response.data.data was a direct array
- After:  response.data.data is { items: [...], meta: {...} }

The old code assumed the array format and crashed with
"items.map is not a function" on Docmost 0.25+.

Fix normalizes both formats for backwards compatibility.
