Subject: [PATCH] fix(build): exempt build scripts and proc-macros from release
 strip
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`wasm-pack build --release` died with "can't find crate" for rustversion,
then thiserror_impl, then every other proc-macro. Cargo strips debuginfo
from release artifacts by default and on macOS that takes the metadata
proc-macro dylibs need to be loadable with it, so rustc could no longer
open them.

Debug builds are unstripped, which is why the whole test suite stayed
green while the browser REPL could not be built for production at all.

Stripping buys nothing for build scripts and proc-macros, so
[profile.release.build-override] exempts them; release binaries stay
stripped.

Also pins wafer-core to 0.2.3 in wafer-web and wafer-cli — both still
asked for 0.2.1. The caret requirement resolved, so nothing broke.

+## [0.2.3] - 2026-08-06
+
+### Fixed
+
+- **Release builds of `wafer-web` no longer fail on proc-macro loading.**
+  Cargo strips debuginfo from release artifacts by default, and on macOS
+  that also strips the metadata proc-macro dylibs need to be loadable, so
+  `wasm-pack build --release` died with `can't find crate` for
+  `rustversion`, `thiserror_impl` and every other proc-macro. Build
+  scripts and proc-macros gain nothing from stripping, so
+  `[profile.release.build-override]` now exempts them; release binaries
+  stay stripped. Debug builds were never affected, which is why the test
+  suite stayed green while the browser REPL could not be built for
+  production.
+- `wafer-web` and `wafer-cli` requested `wafer-core` version `0.2.1`
+  while the workspace had moved to `0.2.2`. The caret requirement still
+  resolved, so nothing broke, but the pin is now kept in step.
+
 ## [0.2.2] - 2026-08-06
