agra 66bdc70bf1 test: group examples into per-category folders
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`) binds a literal (`Vec(3, i64)`) and an
// integral-float named const (`Vec(L, i64)` with `L : f64 : 4.0`) to the same
// integer a plain `4` would — the value-param arg folds through the shared
// const-int evaluator, so the integral-float rule (F0.4 attempt 8, Agra ruling)
// reaches value params too. The folded value is the array length `[K]i64`.
//
// The bind is range-checked against the declared `u32` (an out-of-range arg is a
// clean compile error — see 1134); a valid in-range value binds normally.
#import "modules/std.sx";
