v3: `a << x` copies in depth the arrays inside the struct `x`, while `[x]`, `a << [x]` and the stable compiler share them

v3, json2: residual per-struct cost after #29364 — ~57 ms of `monomorphize` and ~21 KB of C per struct (200 structs → 12.3 s)

v3, veb: route dispatch is monomorphized per controller — 16 controllers × 8 routes → 42k generated C lines, ~0.11 s monomorphize per controller

v3, orm: per-model monomorphization costs ~0.19 s and ~120 KB of C (47 models with one `select` each → 8.9 s in `monomorphize`)

comptime: evaluate `@[comptime]` calls in `const` initializers and emit the value as static data; today every such const is computed in `_vinit`, and enum values ignore the result's integer width

error() heap-allocates a MessageError on every call; provide a zero-alloc sentinel error like `none` for hot not-found paths

Performance: array.slice() marks the source buffer (mark_buffer_has_slices) on every slice — ~13% of a hot loop for transient read-only views
