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.

// Zero is a context-dependent count. An array dimension and a generic
|
|
// value-param count both ACCEPT zero — `[0]T` is a valid empty (zero-length)
|
|
// array, and `Box(0)` is a length-0 instantiation. (A `Vector` lane count
|
|
// rejects zero — see 1505.) This pins the zero-accepting half of the
|
|
// context-dependent count rule documented in specs.md (Array Types).
|
|
//
|
|
// Regression (F0.4 attempt 12): the spec previously claimed every count must be
|
|
// "positive integral", which wrongly implied `[0]T` / `Box(0)` are illegal.
