HTTP Record/Replay (VCR), moved out of Aether

The Servirtium record/replay engine that used to ship in the Aether stdlib as std.http.server.vcr has moved to its own repository:

https://github.com/aether-lang-org/servirtium-vcr

That monorepo is now its authoritative home, the VCR core (core/vcr.ae, core/embed.ae, core/aether_vcr.c) plus its language bindings (.NET, Go, Java, Rust, JavaScript, Python, Ruby, PHP, Elixir, Dart, Haskell, Pharo) and the Servirtium interop suites live there together.

Why it moved

VCR served its purpose inside Aether: it shaped and hardened the HTTP server (port-0 binding, background/quiet serving, chunked decode, the --emit=lib PIC runtime and aether_vcr_embed_* C ABI). Now that the server is solid, the record/replay engine belongs with the cross-language bindings it exists to serve, not in the language's standard library.

Nothing in the Aether language or the rest of the stdlib depended on it, so the removal has no effect on the stdlib surface.

If you used std.http.server.vcr

Depend on the servirtium-vcr monorepo and import core.vcr (the module was renamed from module.ae to vcr.ae). The API is the same one documented here previously, and has since gained untaped() (don't-record / serve-404 paths), see the monorepo's core/TODO.md.

What stayed in Aether

The pure std.http.client behaviour the VCR work motivated remains in the stdlib and keeps its own coverage here, e.g. transparent de-chunking of Transfer-Encoding: chunked responses (tests/integration/http_client_dechunk/).

History

CHANGELOG entries for the VCR work done while it lived here (the 0.181 embed ABI and global -fPIC runtime archive, 0.183 chunked de-chunk, 0.187 embed-surface + strict-ignore) are retained as project history in CHANGELOG-archive.md.
