…lback Adds a real-time Soroban dependency-resolution proxy that fetches crate releases from crates.io, caches them in Redis under a 6-hour TTL, falls back to the curated snapshot when crates.io is unreachable, and surfaces a version compatibility matrix warning students about deprecated soroban-sdk combinations. Exposes GET /dependencies/proxy/:crate. Closes StellarDevHub#1127

Summary
Replaces static mock Cargo dependencies with a live, caching crates.io proxy for real-time Soroban dependency resolution (issue #1127).
src/services/cratesio-proxy.tsfetches crate manifests fromhttps://crates.io/api/v1/crates/<name>using only Node built-ins.cratesio:<name>(CRATESIO_CACHE_TTL_SECONDS), so crates.io is hit at most once per 6h per crate.compatibilityWarnings()flags deprecated/incompatiblesoroban-sdkcombinations (e.g.soroban-auth,stellar-xdr).GET /api/v1/dependencies/proxy/:cratereturns live release metadata + compatibility warnings.DependencyRegistryProvidercontract, so services can swap it in without code changes.src/services/cratesio-proxy.test.ts) — compatibility warnings, cache keys, disabled/fail-safe fallback.Closes #1127
