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.

// Assigning to a field that does not exist on a struct produces the same
|
|
// `field 'X' not found on type 'Y'` diagnostic as the read path (1100), and
|
|
// exits 1 — never the `.unresolved` LLVM-emission panic, never a silent store
|
|
// into a neighbouring field.
|
|
//
|
|
// Regression (issue 0094): the lvalue field lookup left `field_ty = .unresolved`
|
|
// (lowerAssignment's assignment-target path) or silently GEP'd field 0 as `.i64`
|
|
// (lowerExprAsPtr's fallback / lowerMultiAssign's struct loop), so a missing-field
|
|
// store either built a pointer-to-`.unresolved` that panicked at LLVM emission or
|
|
// silently wrote field 0. All three lvalue sites now emit the field-not-found
|
|
// diagnostic: the assignment-target path (`p.q`), the nested lvalue-pointer path
|
|
// (`o.missing.a`), and the multi-target store path (`p.r, y`).
