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.

// A BARE generic struct INSTANCE method (`x.tag()`) must dispatch to the method
|
|
// authored alongside the instance's layout — the single bare-VISIBLE author —
|
|
// NOT the global last-wins `fn_ast_map["Box.tag"]`, which a NON-visible
|
|
// 2-flat-hop same-name template's method can win.
|
|
//
|
|
// `b.sx` declares a one-field `Box($T)` (size 8) whose `tag` returns `self.x+8`,
|
|
// and itself flat-imports `c.sx`, whose two-field `Box($T)` (size 16) declares a
|
|
// `tag` returning `self.x+16`. This file flat-imports ONLY `b.sx`, so `b.Box` is
|
|
// one flat hop away (visible) and `c.Box` is two hops (NOT bare-visible).
|
|
//
|
|
// Regression (Phase E4 finding #1, instance-method site): the static head
|
|
// `Box(i64).make(7)` already selected `b.Box` for the layout (size 8), but the
|
|
// instance method `x.tag()` resolved by bare template name in `fn_ast_map`, so it
|
|
// ran `c.Box.tag` (returning 7+16=23) on the b instance. Fail-before printed
|
|
// `size=8 tag=23`; with body-author ≡ layout-author it runs b's `tag` (7+8=15).
