…tization Recreate the PR #734 hardening on a fresh main-based branch: resolve callback hosts once off-loop, reject non-global/mixed DNS answers, pin connections to validated numeric addresses (preserving Host/SNI/hostname verification and disabled redirects), bound dispatch to three addresses under one deadline without retrying a transmitted POST, and CR/LF-sanitize untrusted callback and exception log values.

Recreates the PR #734 cloud-callback hardening on a fresh branch cut from current
main, so the change carries clean provenance (the original PR is blocked only by its historical pre-dispatch boundary, not by code issues).Changes to
src/youtube_extension/backend/cloud_api_endpoints.py(+ tests intests/unit/test_cloud_routes.py):The PR #734 diff was applied onto current
mainwith a 3-way merge; the intervening #1361 change (Cloud Tasks auth before payload validation) is preserved alongside the hardening. Note: the session was cut off before the focused suite (tests/unit/test_cloud_routes.py) could run in this environment — please rely on CI for verification. The same diff passed CI, Coverage, CodeQL, Security/Secret scans, Dependency Review, and CodeRabbit review at PR #734's head (122 focused tests passed there).
