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 `-> !` main entry-point wrapper (ERR step E4.2). A pure-failable
|
|
// main that lets an error reach the function boundary exits 1 and prints the
|
|
// unhandled-error header (with the tag name, via the always-linked tag-name
|
|
// table) plus the return trace to stderr — instead of the old behavior of
|
|
// returning the raw tag id as the exit code with no diagnostic. A successful
|
|
// run (no escaping error) exits 0.
|
|
//
|
|
// Note: the header + trace go to stderr. The test runner merges stderr+stdout,
|
|
// so the snapshot shows them interleaved with the `print` (stdout) lines.
|
|
// Frame locations are placeholders until DWARF (ERR E3.0); count + ordering +
|
|
// the tag name are already meaningful. Expected exit code: 1.
