Fix remaining test runners for CEK-default mode: override to tree-walk
...
run_type_tests.py, run_signal_tests.py, run_continuation_tests.py all
needed the same sx_ref.eval_expr/trampoline override to tree-walk that
was applied to the CEK test runners. Without this, transpiled HO forms
(ho_map, etc.) re-entered CEK mid-evaluation causing "Unknown frame
type: map" errors. All 186 tests now pass across 5 suites.

Implement explicit CEK machine, continuations, effect signatures, fix dynamic-wind and inspect shadowing
...
Three-phase foundations implementation:
Phase A — Activate dormant shift/reset continuations with 24 SX-native tests
covering basic semantics, predicates, stored continuations, nested reset,
scope interaction, and TCO.
Phase B — Bridge compile-time effect system to runtime: boundary_parser extracts
46 effect annotations, platform provides populate_effect_annotations() and
check_component_effects() for static analysis. 6 new type tests.
Phase C — Explicit CEK machine (frames.sx + cek.sx): evaluation state as data
({control, env, kont, phase, value}), 21 frame types, two-phase step function
(step-eval/step-continue), native shift/reset via frame capture. Bootstrapper
integration: --spec-modules cek transpiles to Python with iterative cek_run.
43 interpreted + 49 transpiled tests passing.
Bug fixes:
- inspect() shadowed by `import inspect` in PLATFORM_ASYNC_PY — renamed to
`import inspect as _inspect`
- dynamic-wind missing platform functions (call_thunk, push_wind!, pop_wind!) —
added with try/finally error safety via dynamic_wind_call
