Move examples/*.sx and their expected/ snapshots into per-category subfolders (examples/<category>/...). Folder = leading filename token, with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus runner and LSP sweep now discover each category's expected/ dir, while issues/ stays flat. Example 1058's repo-root-relative companion import is made file-relative. Path strings embedded in 164 snapshots were regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// A FAILED value-param bind on a type-RETURNING FUNCTION must emit exactly its
|
|
// own diagnostic and NOT cascade a bogus `field '…' not found on '<fn>'` when the
|
|
// binding is later field-accessed. The type-fn binder must poison the binding to
|
|
// `.unresolved` (the diagnosed-poison sentinel) — exactly like the struct binder —
|
|
// so the downstream `.len` is suppressed, not reported as a second error.
|
|
//
|
|
// Regression (issue 0083): the type-fn path (`instantiateTypeFunction`) fell
|
|
// through to an empty-struct placeholder named after the function on a failed
|
|
// value-param bind, so `a.len` produced a second `field 'len' not found on
|
|
// 'MakeC'` error. The struct binder already returned `.unresolved` here; the
|
|
// type-fn binder now matches it. Three failure modes, three clean diagnostics,
|
|
// zero field cascades:
|
|
// - value-param overflow via an aliased integer constraint (`$K: Count`),
|
|
// - a non-const value-param arg (`get()`),
|
|
// - an unknown TYPE arg (`NoSuchType`) — must still report the unknown type.
