feat(MWP-5): bounded 503 retry loop in fetch_mpack with Retry-After honor

Phase 3–5 implementation: - Extract HttpTransport._fetch_mpack_once from fetch_mpack (single-attempt body) - Add retry loop in HttpTransport.fetch_mpack: honors Retry-After, tracks total_waited against retry_budget_s, prints progress to stderr - Add --retry-timeout / --no-retry flags to clone, fetch, pull - Improve terminal 503 message in all three commands (retryable JSON marker) - Tests MWP5_07–MWP5_18 all green (19 total, zero regressions)
