DESKTOP-RTLN3BA\$punk 62260125f7 feat(03b): add BYO custom proxy provider + bounded crawler rotation-retry
Add CustomProxyProvider (single endpoint or rotating pool via Scrapling ProxyRotator), registered as 'custom' alongside anonymous_proxies and selectable via PROXY_PROVIDER. Adds is_pool_backed to the ProxyProvider ABC + a zero-arg package helper. The web crawler does a bounded one-per-tier is_proxy_error rotation-retry gated on is_pool_backed() (single-endpoint providers no-op). Config/.env.example gain CUSTOM_PROXY_URL(S). Zero-arg getter contract unchanged for all consumers. Documents the proprietary boundary test (generic proxy infra stays Apache-2). Tests: provider, registry, crawler rotation (16).

"""Unit tests for proxy provider selection (Phase 3b).
``PROXY_PROVIDER`` selects the single app-wide provider; ``custom`` is now
registered alongside ``anonymous_proxies``, and unknown values still warn and
fall back to the default.
