Build Markdown for a backlink-aware fillable note without writing it.
AI agents call note_build to retrieve information from Knowledge Wiki without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool generates/constructs Markdown content in memory but explicitly does NOT write it to disk. It has no side effects — it only produces a string output. This is effectively a read/compute operation with no persistent changes.
