The early dependency check only verified lamdera/core was present, so projects missing lamdera/codecs (e.g. elm-pages) hit an opaque Map.! crash during JS codegen. Now Checks.hs also validates that lamdera/codecs is reachable, and the graph lookup in JavaScript.hs uses Map.findWithDefault to produce a descriptive message naming the exact missing global. Fixes lamdera#59.
