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.

// Array-typed `::` constants are IMMUTABLE GLOBALS: one storage, reads
|
|
// GEP it, the emitter marks it constant, dead-global elimination drops
|
|
// unused ones. Typed (`K : [4]i64 : .[...]`) and untyped (`A :: .[...]`,
|
|
// element type inferred — all ints i64; any float promotes the element
|
|
// type to f64 with ints converting exactly; bool/string homogeneous).
|
|
// Element shapes cover nested aggregates. Reads are normal array values:
|
|
// indexing, .len, by-value copies (independent of the const), passing to
|
|
// fixed-array params, and @-address (reads through *[4]i64 — issue 0117).
