Per-chunk renderChunk invocations run concurrently (try_join_all in
render_chunks.rs), but every invocation redefined the getter on the one
cached renderChunkMeta, so an async hook that resumed after a sibling
settled executed the sibling's closure: on the threadless flavor a valid
in-hook read hit the sibling's released box (or, since 984ce9d, its
settled deny), and on lazy flavors it silently minted over the sibling
chunk's code — the latter predates this branch (the shared meta is from
#3999/#7943). The getter now lives on a per-invocation wrapper that
shares only the cached chunks map, so each hook sees its own code, cache,
and settled flag on every flavor.

Proven fail-then-pass on both flavors with a deterministic two-chunk
interleave: threadless previously threw "no longer usable" on a valid
in-hook read; native previously returned the sibling chunk's content.

… to main

None of these hunks is needed by the runtime port. Each goes back to main's
code here; the real fixes among them can land as their own PRs on main.

- parallel_js_plugin_registry.rs and its two callers: main's registry
  (the id-reuse and take() hardening has no failing path through the
  public API, and wasm never reaches it)
- binding_output_asset.rs: native asset bytes are a Node Buffer again
  (BufferSlice::copy_from); the wasm JS-owned copy stays
- binding_magic_string.rs: BindingMagicString<'a> again; the 'static alias
  only served an old napi pin. dropInner and the consumed flag stay
- rolldown_error downcast: main's downcast; the chain() walk served a
  shared close error type that no longer exists
- bindingify-output-hooks.ts: one shared renderChunk meta object again, and
  the native-magic-string-interleave fixture goes with it. The shared
  getter is a real main bug (#3999/#7943) and gets its own PR on main
- error.ts isBindingErrors helper and the devtools sessionId JSDoc in
  input-options.ts: main's text. The nullish thrown-value fix in
  getErrorMessage stays (WASI keeps the thrown value)

No #[napi] signature changed; the native build leaves binding.d.cts as is.
