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.
