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.

// Tuple element assignment + named tuples.

// - `t.0 = v` writes one element in place (was a known gap: the lvalue path
|

// looked the element up by name via getStructFields and left the pointee
|
|
// `.unresolved`; now it indexes the tuple positionally like the read path).
|
|
// - Named tuples `(x: T, y: U)` keep their field names through parsing and

// type resolution, so `t.x` reads/writes by name (and `.0` by position).
