v1.0.0

Added

• finite typed pgxpool configuration with secret-safe validation and panic
  containment for malformed DSNs
• fail-fast or lazy startup, bounded acquire, health, statistics, liveness, and
  shutdown operations with direct native pool access
• context-aware transaction and savepoint runners with panic-safe rollback and
  preserved callback, commit, and rollback errors
• SQLSTATE, constraint, cancellation, timeout, connectivity, saturation, and
  retry-advisory classification without flattening original errors
• bounded lifecycle observations, safe slog, and optional OpenTelemetry
  metrics that omit SQL, arguments, DSNs, and raw database errors
• Testcontainers support plus PostgreSQL 14-18 integration evidence for
  contention, deadlock, serialization, cancellation, server timeouts,
  constraints, transaction loss, stop/restart, saturation, shutdown, and cleanup
• executable sqlc, go-migrations, service, and worker adoption examples
• exact production coverage, race, leak, fuzz, benchmark, safety, lint,
  vulnerability, documentation, compatibility, and release automation
