Xuanwo 685cb01d6d feat: add grouped function column bindings (#3994) ...

Function applications from the canonical remote contract cannot
currently declare scalar or grouped computed-column outputs atomically.

This adds the remote-only declaration contract for scalar,
struct-as-one-column, and expanded named-struct outputs. It validates
result mappings, fixes exact input/output Arrow schemas in the request,
persists grouped sibling metadata, and keeps local Function execution
unsupported. Unknown newer application or binding metadata remains
readable, while schema-changing mutations fail closed instead of
rewriting it.

Stable Lance field IDs are deliberately not a declaration prerequisite
in this slice. Inputs bind by parameter name and field path; Sophon
remains responsible for exact-version validation, atomic all-NULL
sibling creation, binding identity and revision allocation, and
persisted output identities.
