fix(knowledge): address PR feedback on Cohere reranker controls

- Drop required:true on apiKey field — server has BYOK→env→rotation fallback
  chain, so self-hosted users with COHERE_API_KEY env should not be blocked
- Drop .min(1) on rerankerApiKey contract field so empty strings coerce to
  undefined via the transform (matches the existing query field pattern)
- Log a warning when rerankerInputCount is clamped up to topK so users notice
  their setting was overridden

+## What are Skills?
+
+Skills are folders of instructions, scripts, and resources that AI agents load dynamically to improve performance on specialized tasks. Each skill is self-contained with a `SKILL.md` file containing instructions and metadata.
+
+For more information about the Agent Skills standard, see [agentskills.io](http://agentskills.io).

+3. (Optional) Add scripts, examples, or other resources
+
+**Required fields in SKILL.md:**
+```yaml
+---
+name: my-skill-name
