Orkuncakilkaya b7745a4600 refactor(lang): rename the str type (and stringify builtin) to string
Expand the abbreviated string type and its conversion builtin to the full
word everywhere:
  str            ->  string        (the immutable-string type)
  str(x) -> str  ->  string(x) -> string   (the stringify builtin;
                                            what `{…}` interpolation calls)

Types are recognized by identifier, and llty maps both spellings to LLVM
`ptr`, so this is an atomic source rewrite: type annotations, the Ludic
type tags, the builtin name/dispatch, and the interpolation desugar, plus
the grammars, LSP, docs (type-str -> type-string, fn-str -> fn-string), and
inventory. int/bool stay (universally accepted, like Math).

Reseeded; C-free fixpoint holds; all suites green (45/24/29); site + check.py OK.

Splits <code>s</code> at every occurrence of the non-empty separator <code>sep</code> and returns the pieces as a <code>[]string</code> — the inverse of <code>Text.join</code>. Adjacent separators yield empty pieces, and a string with no separator returns a one-element list holding the whole string. Use it to parse CSV rows, command arguments, or delimited save data.
