Merged into #647 (feat/smart-configurl-registry). SDK tools, examples, and existing SmartDialer/Mobileproxy construction now use NewDefaultRegistry, New[T], and RegisterBase.

The combined #647 contains the registry API, deprecations, and these caller migrations, resolving the deprecated-API errors in CI. SmartDialer/Mobileproxy extension options remain in #649, stacked directly on #647.

The connectivity tool preserves its tracing dialer lifetime and per-operation tracing. This migration still uses local registries in SmartDialer; configurable shared registries are introduced separately in #649.

Validation: this PR's head, 563cea409e12eb2494f67d4e20524a0d162d1c9f, passed GitHub's Build and Test workflow and was used to fast-forward #647 during consolidation. A fresh local full x race suite and staticcheck also pass. Module files and dependencies are unchanged.

Confidence Score: 5/5

[Medium impact] This migration appears safe to merge.

Summary

Migrates tools, examples, mobileproxy, and smart from deprecated providers to NewDefaultRegistry, New[T], and RegisterBase.

• Tools, examples, and mobileproxy build config URLs through typed registries.
• SmartDialer searches build transports through typed registries.
• The connectivity tool builds traced transports through registered base dialers.
