[Feature]: get doc info Child table support

[conncampbell]

Description

When getting doc type info, child tables are not retrieved. this causes FAC to not understand that it needs to include child table data when creating documents with child tables.

Use Case

I'm trying to create documents that have child table data, but currently FAC will only create the main document with no child table data.

Proposed Solution

I'm not sure, but I think the method MetadataTools get_doctype_metadata method should include child table metadata.

Alternatives Considered

I've been manually providing the document json for the child tables.

Area

MCP Tools (core, data science, visualization)

Thanks for filing this — confirmed gap, and a real one.

get_doctype_info flows through MetadataTools.get_doctype_metadata. Each field comes back with fieldtype and options, so when a field is Table the child DocType name is technically present in options — but there's no top-level summary, no recursive expansion of the child DocType's own fields, and nothing in the response that says "you must populate these as nested arrays."

Meanwhile create_document's own description explicitly tells the model "First use get_doctype_info to understand the DocType structure, identify required fields and child tables" (create_document.py:44). So we point the model at a tool that can't actually answer the question — that's the bug.

Will ship this in the next release.

Will link the PR here once it's up.
