axios blocked at runtime: 'Class extends value is not a constructor' at module init — a native-builtin base (Error or stream.Transform) is not resolving as a constructor #10662

Found by a package-compilability probe: axios now compiles from real source but fails at runtime, and this
is the single blocker.

TypeError: Class extends value is not a constructor

It throws at axios's module-init time, so one of its extends targets is not resolving as a constructor.

Candidate sites in axios

• AxiosError extends Error
• CanceledError extends AxiosError
• AxiosTransformStream extends stream.Transform
• ZlibHeaderTransformStream extends stream.Transform

The native-builtin bases are the suspects — Error, or stream.Transform served through the
ext-streams/ext-http well-known wrapper dedup path. First step is to narrow which one, since that decides
whether this is new or a manifestation of existing work.

Likely neighbours — check before writing a fix

This cycle has produced a cluster of native-base heritage fixes, and this may be one of them seen from axios's
angle:

• PR fix(runtime): dispatch node:stream super() through any bound-export heritage shape #10649 (Fixes #10448) — node:stream super() via any bound-export heritage shape.
• http.ServerResponse and stream.Readable have empty prototypes: subclasses built with util.inherits + Base.call(this), setPrototypeOf or class extends ServerResponse have no setHeader/end/push (light-my-request / fastify inject() never settles) #10454 — stream.Readable/http.ServerResponse have empty prototypes; a WIP fix there was found to only
  half-work, with ServerResponse still entirely broken (see that issue's comment).
• PR fix(codegen): run field initializers at native-base super() and guard typed Map/Set receivers #10617 — field initializers at a native-base super(), including Error subclasses.
• PR fix(codegen): forward implicit-ctor args to a native base super() reached via require() #10636 — native-base recognition skipped when the extends identifier looks locally shadowed, which inside a
  CommonJS wrapper is every const { X } = require(...). axios is CommonJS, so this one is a strong candidate.

If #10636 or #10649 already fixes it once landed, close this and say so rather than duplicating.
