Arun Kumar Thiagarajan 5a4a69adfc docs(deprecation): add database schema migration patterns (expand/contract) ...

Adds a Database Schema Migrations section to deprecation-and-migration covering
expand/contract, dual-write + batched backfill, additive-first/destructive-last,
tested down paths, and non-blocking index builds. References incremental-implementation
for slicing; reuses the skill's existing Feature Flag Migration pattern.
