fix(async_hooks): complete node suite parity - #8853
Conversation
📝 WalkthroughWalkthroughThe change propagates strictness through dynamic index assignments and typed-array fallbacks. It adds the strict runtime setter and regression tests. The async_hooks suite updates platform-specific providers and lifecycle waits, reaching 195/195 parity. ChangesStrict indexed assignment

Honor strict mode for string primitive receivers.
When obj is a string primitive, js_dyn_index_set_strict returns value before applying strict. A strict assignment to an existing string index, such as "x"[0] = 1, must throw a TypeError. Apply String exotic [[Set]] semantics through strict-aware PutValue handling.

The cross-module twin (extern_func.rs, the issue #608 arm) has always padded missing trailing args with TAG_UNDEFINED; the same-module plain arm sat "one else away" (#7154's own words) unpadded. On the Claude Code bundle — one giant module, so EVERY direct call resolves through the same-module arm — `aP([q])` for `function aP(q, K = !1, _)` handed K/_ whatever d1/d2 held after js_array_from_values: impossible-NaN bit patterns (0xffffffffffffffff) that flowed into truthiness tests and method receivers (`_.get(A)`) and faulted in shape_is_url_search_params / js_is_truthy (~60% of `cc -p` runs SEGV), or silently corrupted the async iteration ("Detected unsettled top-level await", most of the rest). With the padding, `cc -p` runs 30/30 clean: 0 SEGV, 0 hangs, 0 unsettled awaits, node-identical output on every run. The GC-knob correlations the long #8770 investigation chased (scavenge pacing, conservative-scan "fixes") were register-content side effects of the missing padding, not collector bugs. Regression test: an under-applied direct call to a 3-param callee must emit all three double args, the omitted two as the TAG_UNDEFINED literal.

Summary
Completes the
node:async_hooksparity closure tracked by #6764. Strict computedPutValueassignments now preserve their reference strictness through the dynamic index-store optimization, and the remaining platform-sensitive provider/lifecycle fixtures are deterministic on Windows and Unix.The curated async-hooks baseline is now 195/195.
