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.

id: op-interp name: String interpolation category: operators kind: operator sig: text {expr} more tip: A backtick string with {expr} holes, each stringified and concatenated. order: 7

A backtick string `…` is an interpolated string: any {expr} hole inside it is evaluated, converted to text, and concatenated with the surrounding literal parts. Numbers, bools, and fixed values are stringified automatically and string values pass through, so `score: {score}` desugars to "score: " + string(score). It is the readable way to build a message from mixed pieces without hand-writing a + chain. Write a literal brace with {{ or }}.

let status_line: string = `score {score} — health {current_health}/{maximum_health}`
Screen.status(status_line)
print(`wave {wave_number} incoming`)
