feat(conformance): TS vector runner (Jest) + GitHub Actions CI

Adds a TypeScript Jest-based conformance runner that executes all 216
vectors under conformance/vectors/ against @bsv/sdk, achieving 213
passing / 3 skipped (parity_class=intended). Also adds a GitHub Actions
workflow running both Go and TS runners on push/PR to main and
phase2/boundary-specs. Fixes broken @bsv/paymail version ref in
ts-paymail examples so pnpm install succeeds in CI.
