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.

// Cleanup-body control-flow restrictions (ERR step E1.7 follow-up). A `defer`
|
|
// or `onfail` body runs while the block/function is already exiting, so it has
|
|
// no target to transfer control to: `raise` / `try` / `return` / `break` /
|
|
// `continue` are all rejected inside one. The ban is transitive through nested
|
|
// `catch` bodies and loops, but NOT through a nested closure (its own function
|
|
// boundary). `raise` was already banned (E1.3); this adds the other four.
