feat(db): .kc metadata database migration (#140)

Add migration 018_kc_metadata.sql with all tables needed for .kc server-side metadata indexing: - item_metadata: indexed manifest + metadata fields from silo/ directory (tags, lifecycle_state, fields JSONB, manifest info) - item_dependencies: CAD-extracted assembly dependencies (complements existing relationships table) - item_approvals + approval_signatures: ECO workflow state - item_macros: registered macros from silo/macros/ Also adds docs/KC_SERVER.md specification document. Closes #140

+-- Migration 018: .kc Server-Side Metadata Tables
+--
+-- Adds tables for indexing the silo/ directory contents from .kc files.
+-- See docs/KC_SERVER.md for the full specification.
+--
+-- Tables:
+--   item_metadata        - indexed manifest + metadata fields (Section 3.1)
+--   item_dependencies    - CAD-extracted assembly dependencies (Section 3.2)
+--   item_approvals       - ECO workflow state (Section 3.3)
+--   approval_signatures  - individual approval/rejection records (Section 3.3)
+--   item_macros          - registered macros from silo/macros/ (Section 3.4)
