Surface rename of the signed integer family: s1..s64 become i1..i64
(u1..u64, usize, isize unchanged). 'string' keeps the s-prefix arm in
name classification; width parsing moves to the i-prefix arm next to
isize.
Internal TypeId tags follow the surface (.s8/.s16/.s32/.s64 ->
.i8/.i16/.i32/.i64), as do mono-key mangle fragments (ptr_i64,
tu_i64_bool) and all display/diagnostic formatting (i{d}).
Migrated in the same sweep: stdlib + examples + issue repros + FFI C
companions (shared symbol names like ffi_id_i64), expected
stdout/stderr/ir snapshots, specs.md, readme.md, CLAUDE.md/AGENTS.md,
implementation_plan.md, docs/, issue writeups. Vendored stb_image and
historical flow state left untouched.
zig build test: 426/426; examples suite: 595/595.

// The cleanup-absorption check (ERR step E1.7) is TRANSITIVE: a bare,
|
|
// un-absorbed failable call is rejected no matter how deeply it is nested
|
|
// inside a `defer` / `onfail` body's control flow — through `if` (both
|
|
// branches), nested blocks, and loops. 1049 covers the direct-body case; this
|
|
// pins the recursive arms of `checkCleanupNode` (`.if_expr`, `.block`,
|
|
// `.while_expr`) before A5.2 extracts the pass into its own module.
|
|
//
|
|
// Three bare failables, three rejections; the program never runs (exit 1).
