Adds GEOMETRIC_SCHEMA_EXTENSION.md and provides understated documentation cross-references in SCHEMA.md and README.md.

Specific Notes & Invariants

1. Geometric Schema Extension: Formally specifies optional prospective fields (topological_family, terminal_node_count, terminal_edge_count, graph_invariants, sequence_formula_id) for discrete structural and topological ground truth in drawing recordings.
2. Strict Missing-Value Integrity: Enforces that for multi-clip sequences (Rec01..RecNN), terminal ground-truth counts attach strictly to the primary reference row (Rec01). All intermediate clips (Rec02..RecNN) remain strictly blank; blank numeric values are not zero, preserving the invariant that in-progress clips represent incomplete drawings rather than empty structures.
3. Repository Parity & Zero Payload Changes:
   • Total canonical indexed files remain unchanged at 1,106 records across 425 physical works (work_id).
   • Zero MP4 media files, SHA256SUMS, or existing metadata rows are touched, renamed, or modified.
   • README addition is strictly limited to one subdued sentence under Physical-work correspondence, avoiding any downstream CV dominance over the core archive identity.
