Add tests/key_sources.rs exercising the published KeySource impls end-to-end over real fixture files and the libfreemkv parsers: - KeydbSource: disc-hash lookup from a real keydb.cfg (VUK hit ranks ahead of the universal DK pool), hash miss yields only the pool, missing file is silent/not errored, label + needs_samples, and host-cert serving from a | HC | row (inherent and trait paths). - paths: exe-local search list, default == search head, existing path reflects on-disk state (local-only, no OS fallback). - MapfileSource: persisted # freemkv-uk: keys read back as a terminal Key::Unit, one-shot exhaustion, missing/keyless mapfile offers nothing. - OnlineSource: unconfigured no-op (no network), one-shot latch, metadata, and validate_keyserver_url scheme/SSRF gating. - MultiSource: caller-supplied order/precedence (and its reverse), empty-source skip, needs_samples/errored OR-aggregation, nesting, and a real keydb-then-mapfile precedence chain over fixtures.
