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 generic value parameter (`$K: u32`) bound from a named const or a
|
|
// constant-foldable expression resolves to the SAME monomorphised instantiation
|
|
// as the literal form: `Vec(N, f32)` (N a module const) and `Vec(M + 1, f32)`
|
|
// (a const expression) are both `Vec(3, f32)`. The struct-copy assignment is the
|
|
// proof — it type-checks only because the two spellings name one instantiation.
|
|
//
|
|
// Regression (issue 0083): the value-param binder hand-rolled an `else => 0`
|
|
// switch, so a named-const value arg either fabricated a 0 binding under a wrong
|
|
// mangled name or was rejected outright as "unknown type 'N'". It now folds
|
|
// through the shared const-int evaluator (`program_index.evalConstIntExpr`).
