fathomdb-cli 0.8.21

//! EU-5b RED — `fathomdb doctor warm-cache` CLI subcommand.
//!
//! Per `dev/plans/prompts/0.7.1-EMBEDDER-UNDEFER-HANDOFF.md` §EU-5b step 7.
//! The subcommand invokes the default-embedder loader without opening an
//! engine, so users/CI can warm the cache in a controlled step before
//! `Engine::open` runs.

// EU-5c — env-gate the network-hitting warm-cache integration test. CI
// sets `FATHOMDB_SKIP_NETWORK_TESTS=1` only when the pre-warm step
// fails; the default path runs against the warm cache.
