Add behavioral spec suites for the collection API (~180 cases). Writing them surfaced and fixed real bugs: - (count nil) errored; now 0 (Clojure semantics) - (repeat x) and (repeatedly f) — the infinite 1-arg arities — were unsupported; now return lazy infinite seqs - set equality used deep= (representation-sensitive), so a set of map literals could differ from an equal set built differently; now value-based (each element value-equal to some element of the other) Known limitation filed: phm-typed maps (from hash-map) used as set elements / map keys hash by identity (map *literals* are structs and work). jpm test green.
