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.

// Regression (issue 0100 F2): lowering a QUALIFIED imported function whose
|
|
// body terminates must leave the CALLER's lowering state untouched.
|
|
//
|
|
// `m :: #import …` registers `m.foo` as a module-qualified alias with a unique
|
|
// FuncId (the identity fix, issue 0100 / example 0719) and lowers it through
|
|
// `lazyLowerFunction`'s null-FuncId `lowerFunction` path. `foo`'s body folds
|
|
// `if true { return helper(); }` to an unconditional return, so its lowering
|
|
// ends with `block_terminated = true`. The null-FuncId path used to restore
|
|
// every saved caller field EXCEPT `block_terminated`, so that flag leaked back
|
|
// into `main`, and `main`'s own trailing `print` / `return 0` were treated as
|
|
// dead-after-terminator — the compiler rejected `return 0` with "body produces
|
|
// no value". The fix routes all exit paths through one save/restore defer, so
|
|
// the qualified alias is transparent to the caller. (`helper` also lives in
|
|
// m.sx's own flat import, exercising the F1 source-context restore too.)
