- Rename module to gitea.iliadenisov.ru/developer/scrabble-solver so it can be consumed as a versioned dependency (no go.work replace / CI clone). - De-internalize wordlist and dictdawg as public packages. - Remove cmd/builddict, dictprep/, the dictionaries submodule and the dawg Makefile: the word-list parsing and DAWG build now live in the separate scrabble-dictionary repository, which publishes the DAWG set as a release artifact. - internal/dict loads the committed dawg/en_sowpods.dawg fixture for cmd/stress. - Update README/CLAUDE docs accordingly.
