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.

// Free-function dot-calls are OPT-IN. Two opt-in spellings:
|
|
// name :: ufcs (params) { body } — the fn itself is dot-callable
|
|
// name :: ufcs target; — dot-callable (renaming) alias
|
|
// A plain fn is callable directly or via `|>` only (see 1166 for the
|
|
// rejection). Generic ufcs fns dispatch through normal monomorphization,
|
|
// and the plan-side return type binds from the receiver (structured
|
|
// params like `[]$T` included).
