Closes the remaining three F0.6 findings so the universal backtick raw identifier holds in BOTH classifiers and at EVERY parser construction site. 1. Struct-body constants thread is_raw + name_span. The struct-body const forms (untyped `` `s2 :: 5 `` and typed `` `s2 : T : v ``) built the const_decl node without name_span/is_raw, so a backtick const was falsely rejected and a bare reserved-name const caretted at 1:1. They now capture both. Structural cure: `ast.ConstDecl`'s name_span + is_raw carry NO default, so the compiler rejects any construction site that omits them (mirrors checkBindingName's required `is_raw` arg). FnDecl keeps its defaults — every parser fn_decl routes through parseFnDecl whose `name_is_raw` is a required parameter (equivalent guarantee). 2. Raw identifier in TYPE position flows through the normal continuations. parseTypeExpr no longer returns a terminal type_expr for a raw atom; the raw flag rides the atom through the qualified-path / Closure / parameterized continuations, so `` `s2(s64) ``, `` *`s2 ``, `` ?`s2 `` all parse. ParameterizedTypeExpr carries is_raw; resolveParameterizedWithBindings skips the `Vector` intrinsic when raw. 3. sema/LSP (the second classifier) honors is_raw. Type.fromTypeExpr returns null for a raw type_expr; resolveTypeNode skips the builtin classifier when raw; resolveTypeNameStr takes a skip_builtin arg threaded from te/id.is_raw (compound inner names pass false). A backtick reserved-name annotation now resolves to the user type in the editor index, not the builtin. Tests: examples/0156 (struct-body const), 0157 (parameterized raw type + wrappers), 1142 (bare struct-body const errors, caret on name); src/sema.test.zig pins the LSP raw-type resolution (fail-before verified). Gate: 365 unit tests, 429 examples, 0 failed.

// Backtick raw-identifier escape at a STRUCT-BODY constant — both the untyped
|
|
// `` `name :: value `` and the typed `` `name : T : value `` forms. A struct
|
|
// member constant is a binding site like any top-level const (examples/0153),
|
|
// so a reserved type spelling (`s2`, `u8`) needs the backtick to be used as the
|
|
// constant's name; the value is read back via `Holder.`name`. A *bare*
|
|
// reserved-name struct const still errors with the caret on the name (see
|
|
// examples/1142). The backtick is never part of the name's text.
|
|
// Regression (issue 0089 — attempt-5: struct-body const decls thread is_raw +
|
|
// the precise name_span, previously dropped to a false reject / 1:1 caret).
