feat(sandbox): extend managed allowlist with build + dataset egress domains

Widens the Bash-subprocess egress allowlist for common agent workflows:
Anthropic direct (api, statsig), Ubuntu mirrors, NodeSource/deb for Node,
crates.io (Rust), yarn, full npm + pypi groups, GitHub release assets,
and wildcards for geoboundaries, googleapis, jsdelivr — covers dataset
fetches and CDN-backed library assets that previously failed silently.
