Now that we have C99 designated initializers, we don't need the
STACKLESS_DECLARE_METHOD magic any longer. Replacing it with explicit
initializers has several advantages:
- faster startup time
- less magic, code is simpler to reason about
- no memory leak
- no initialization race for sub-types between init_stackless_methods()
  and PyType_Ready().

…es Phase 3D

Per supervisor 2026-04-27T19:31:15Z + theologian 2026-04-27T19:30Z
audit. The bisect bound "Phase-3D-start (42d0a0b)..HEAD" cited in
prior revisions is INCORRECT — gen_simple was already at 0.75x in
docs/benchmarks/x86_64_abba_2026-03-31.md, predating Phase 3D Step 1
(2026-04-01) by 1 day. Companion arm64_abba_2026-04-01.md annotation
hypothesizes "Generator resume path has JIT infrastructure overhead
(deopt trampoline)" as contemporaneous root-cause candidate.

Updates Status section, Stability evidence table (adds 2 pre-Phase-3D
entries + revised range/coverage), and Resumption gate step 2 (revised
bound + deopt-trampoline shortcut candidate). Pythia-python#200/python#202 risk of
bisect resolving inside HirBuilder/Phase-4 surface is reduced — the
introducing commit predates that surface entirely.
