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.

// An `inline for` / `for` range bound is a range ENDPOINT, not a count, so the
|
|
// count negative-rejection rule does NOT apply to it: negative endpoints are
|
|
// valid and an empty/inverted range simply runs zero iterations.
|
|
//
|
|
// Regression (F0.4 attempt 11, Agra ruling): the spec wrongly lumped inline-for
|
|
// bounds with counts (array dim / Vector lane / value-param), which reject
|
|
// negatives. Bounds are exempt — `inline for -2..1` iterates -2,-1,0 and an
|
|
// integral-float empty range `0..(-2.0)` runs zero iterations. Comptime and
|
|
// runtime loops must agree.
