Expand the function-declaration keyword to the full word across the whole
language and toolchain:
fn name(...) -> T { ... } -> function name(...) -> T { ... }
Done as a self-hosting migration: teach the parser both spellings, reseed,
rewrite every .ludic definition to `function`, then drop `fn`. The compiler
now rejects `fn`. Touches the parser, all selfhost/tools/runtime/example/test
sources, the grammars (TextMate shared+vscode, ludic_syntax.h, JetBrains
LudicTokens.kt), the LSP and formatter, the Python doc/vocab tools
(check-impl, check-docs, validate, palette, test-lsp), and the docs
(fences, prose, kw-fn -> kw-function).
Reseeded; C-free bootstrap fixpoint holds. All suites green (45 regression,
24 self-host, 29 tool); the docs site generates and check.py passes.

One `print` instead of two C-style names: `print(x)` writes an int OR a string
followed by a newline, dispatching on the operand type (int -> %d, string ->
%s). `print(int)` emits byte-identically to the old print_int, so every existing
call and every smoke-test output is unchanged.
print_str was only ever the raw IR-to-stdout dump in ir_flush (no newline), which
is not "printing a line" — so it now uses file_write to a new file_stdout()
stream, keeping the emitted IR byte-for-byte identical. That frees `print` to
have consistent always-newline semantics.
Two reseeds: (A) add print + str + file_stdout keeping the intrinsics; (B)
migrate the 61 print_int calls to print, ir_flush to file_write(file_stdout()),
and delete print_int/print_str (+ the now-dead @.fmt_str). str(x) (the
interpolation converter from 7d) is now also a documented standalone builtin.
Vocabulary: print/str/file_stdout in, print_int/print_str out (ludic_syntax.h,
grammar, LudicTokens.kt). LANGUAGE.md updated. Reseeded (22551 lines); C-free
fixpoint holds; goldens identical; 18/18; vocab + doc-fences clean.

`struct` and `property` had identical syntax and differed only in semantics, so
they are now one keyword: `property`. How a property is stored follows from how
it is used —
- listed in a `model` or attached by `spawn` -> an ECS component, kept in the
engine's per-entity @S_/@H_ arrays and bound in queries (as before);
- constructed with `new` -> a heap record with reference
semantics (what `struct` used to be).
A program that declares only `property` records and functions — no `model`, no
`handler` — is not an ECS program: it gets record layouts and `new`, but no
entity storage, allocator, snapshot, or runtime splice. This is exactly the
shape of the Ludic compiler itself, whose Node/Tok/Buf/Val are now `property`.
Mechanics:
- record layout (%Cmp_) now always emitted in the header (emit_head), so `new`
works with or without the ECS; the per-entity arrays stay in
emit_ecs_storage. %Str_ is gone — one layout prefix.
- has_ecs() is now `has_systems() or has_models()`, not "any component"; a
property alone no longer drags in the ECS runtime. Added has_models().
- emit_new / member access / layout_ty / layout_node collapse onto find_comp.
Dropped struct keyword, parse_struct, find_struct, is_struct_ty, N_STRUCT
emission (the const stays at kind 0, the default node kind).
Migration done as two reseeds (the old compiler treats any component as ECS, so
it cannot see `property` records in the compiler source until has_ecs is fixed):
A) teach the compiler property-as-record + fix has_ecs, keeping `struct`;
B) migrate the compiler's own records to `property` and remove `struct`.
selfhost/tests/structs.ludic migrated (still prints 7 9 109 2 42). Vocabulary
drops `struct` from DECL (ludic_syntax.h, grammar, LudicTokens.kt). LANGUAGE.md
"Records" section rewritten. Reseeded (21613 lines); C-free fixpoint holds;
goldens identical; 17/17; vocab + doc-fences clean.

Self-hosted compiler (selfhost/*.ludic), runtime, examples, editor tooling,
and docs. Phase 1 of the syntax-redesign cohesion pass has landed:
edge-system fix, signature-query, when-alias, and the documentation truth-pass.
Suite green (14/14), C-free bootstrap fixpoint holds.
