feat: add 43 new SQL functions in ruvector-postgres v0.3.0 (ADR-044)

Integrate 5 workspace crates (ruvector-solver, ruvector-math,
ruvector-attention, sona, ruvector-domain-expansion) as 6 feature-gated
modules exposing solver, math distances, TDA, extended attention, Sona
learning, and domain expansion — bringing total to 143 SQL functions.
Docker image verified with all functions passing.
