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.

// Failable `or` chain propagation (ERR step E2.4b). When every operand of a
|
|
// `try … or try …` chain fails and there is no value terminator, the final
|
|
// failure propagates to the enclosing function — here `main`, so the E4.2
|
|
// entry-point wrapper prints the unhandled-error header + return trace to
|
|
// stderr and exits 1. Each failed attempt contributes its `raise` frame plus
|
|
// the chain-attempt frame, so three all-failing attempts leave six frames
|
|
// (locations are placeholders until DWARF / E3.0). Expected exit code: 1.
