The WASM_BUILD_STD=0 approach caused panic_impl duplicate errors because
wasm32-unknown-unknown pre-built sysroot includes std, conflicting with
pezsp-io's panic handler in wasm runtime builds.
Local testing confirmed that wasm32v1-none + no build-std + serde fork
works correctly. The wasm-builder creates a separate cargo project that:
- Excludes std/default features from the runtime
- Has no client crates in the dependency tree
- Properly uses the serde fork for target_os="none" handling
Restore rustup target add wasm32v1-none in all 14 CI build jobs and
remove all WASM_BUILD_STD=0 overrides.
wasm32v1-none pre-built sysroot lacks std, causing memchr compilation
failure. Instead, disable build-std via WASM_BUILD_STD=0 and let
wasm-builder use the pre-built wasm32-unknown-unknown sysroot which
includes std.
Affected: 11 build jobs in build-publish-images.yml, 2 benchmark jobs
in check-pezframe-omni-bencher.yml.
The paritytech CI container lacks the wasm32v1-none target, causing
wasm-builder to fall back to wasm32-unknown-unknown with -Z build-std.
Combined with our serde_core fork, this creates a duplicate lang item
error for alloc crate.
Fix: Add rustup target add wasm32v1-none to all WASM-building jobs.
For check-only jobs (bench checks, docs, each-crate), add SKIP_WASM_BUILD=1.
Also fixes test-deterministic-wasm wasm blob path to work with either target.
* docs: update workflow plan with completed CI fixes
* fix(ci): remove wasm32v1-none target installation to fix serde_core compilation
This removes the explicit `rustup target add wasm32v1-none` step from CI
workflows. When wasm32v1-none is installed, the wasm-builder uses it instead
of wasm32-unknown-unknown, which causes serde_core 1.0.228 to fail compilation
with "relaxing a default bound only does something for ?Sized" errors.
By not installing wasm32v1-none, the wasm-builder automatically falls back to
wasm32-unknown-unknown which compiles successfully.
This aligns with Polkadot SDK's CI configuration which also does not explicitly
install wasm32v1-none.

Fixes getrandom/duplicate lang item errors in WASM builds by ensuring
the wasm32v1-none target is installed before running cargo builds that
involve WASM compilation. This is required for Rust 1.84+ where the
bizinikiwi-wasm-builder uses wasm32v1-none instead of wasm32-unknown-unknown.
Affected workflows:
- tests.yml (quick-benchmarks)
- tests-linux-stable.yml (test-linux-stable-int, test-linux-stable-runtime-benchmarks)
- tests-misc.yml (test-deterministic-wasm)
- build-publish-images.yml (build-linux-stable, build-linux-bizinikiwi)
- check-pezframe-omni-bencher.yml (quick-benchmarks-omni, run-pezframe-omni-bencher)
- Rename CLI argument --pallet to --pezpallet (with --pallet as alias)
- Rename --pallets to --pezpallet, --exclude-pallets to --exclude-pezpallets
- Update benchmark subcommand from 'pallet' to 'pezpallet'
- Rename check-frame-omni-bencher.yml to check-pezframe-omni-bencher.yml
- Update all benchmark scripts to use new argument names
- Update cmd.py to use pezframe-omni-bencher and --pezpallet
