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 qualified generic type head `ns.Box(args)` must instantiate the template
|
|
// AUTHORED by `ns`'s module — not the global same-name template that happened to
|
|
// win the last-wins `struct_template_map`. `main` imports two namespaces that
|
|
// each author a same-name generic `Box($T)` with a DIFFERENT layout (a: one
|
|
// field, b: two fields). `a.Box(i64)` and `b.Box(i64)` must resolve to their OWN
|
|
// module's template (sizes 8 and 16) and be DISTINCT types, so a field unique to
|
|
// b's layout (`y`) is reachable only through `b.Box`.
|
|
//
|
|
// This is the ambiguity escape hatch made real: when a bare `Box(i64)` is
|
|
// ambiguous (two flat same-name authors), the diagnostic tells the user to
|
|
// "qualify the reference"; that advice only works if `ns.Box(..)` actually
|
|
// selects ns's author.
|
|
//
|
|
// Regression (Phase E4): before qualified generic-head selection, the head was
|
|
// stripped to the bare name and read from the global `struct_template_map`, so
|
|
// `a.Box(i64)` and `b.Box(i64)` both instantiated the last-wins template (both
|
|
// size 16) — the namespace qualifier was ignored.
