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.

// Variadic heterogeneous type packs — step 4A final-slice
// follow-up. `type_name(<dynamic-arg>)` where the argument is
// NOT a static type expression (e.g. `list[i]` indexing into
// a `$args`-derived `[]Type` slice) silently folded to "i64"
// because `resolveTypeArg`'s catch-all `else => .i64` lied —
// the kind of silent unimplemented arm the project's REJECTED
// PATTERNS forbid.
//
// The fix: `tryLowerReflectionCall` now splits static vs
// dynamic args via `isStaticTypeArg(node)`. Static → fold to
// const_string at lower time (today's fast path). Dynamic →
// emit `callBuiltin(.type_name, [arg_ref])` for the interp's
// runtime arm to handle.
//
// Type values are comptime-only — the dynamic path only works
// inside a comptime context (`#run` / `#insert`). The test
// runs `walk(42, "hi")` at `#run` time and prints the result.
