research-integrity 1.4.3

The hook and the server are now the shell scripts themselves.

They start no other program, so the directory has no second file to refuse to follow. The server's only tool is scan_text. It does not open a file. The hook warns on five overclaim phrases and blocks only when the current directory has .research-integrity.json with "block": true.

Not claimed. A phrase hit is not proof the sentence is false. The research rules are unchanged.
