Changes:
- Add Rust caching (Swatinem/rust-cache) to all heavy build jobs
- Reduce cargo-check-each-crate from 7 to 4 parallel jobs
- Reduce tests-linux-stable matrix from 6 to 3 jobs
- Set CARGO_INCREMENTAL=0 for consistent caching
- Reduce timeouts from 60 to 45 minutes (cache makes builds faster)
- Remove redundant disk cleanup steps (cache handles this)
Expected improvements:
- 50-80% faster builds after cache is populated
- Lower VPS load (fewer parallel jobs)
- More consistent build times
Affected workflows:
- checks.yml (cargo-clippy, check-try-runtime)
- tests.yml (quick-benchmarks, cargo-check-all-benches)
- tests-misc.yml (test-pezframe-ui, cargo-check-each-crate)
- tests-linux-stable.yml (test-linux-stable)
- docs.yml (test-doc, build-rustdoc)
- Change branch reference from 'master' to 'main' in cargo-check-benches
- Disable test-pezframe-examples-compile-to-wasm (serde_core wasm32 duplicate lang item issue)
- Add SKIP_WASM_BUILD=1 to cargo-check-each-crate
- Update test-deterministic-wasm dependency (remove disabled job)
- Update confirm-required job needs list
The serde_core wasm32 issue is tracked in #355 and affects all wasm32-unknown-unknown builds.
Same issue that disabled check-core-crypto-features in checks.yml.
Add rustup target add wasm32v1-none step to:
- tests-misc.yml: test-pezframe-examples-compile-to-wasm, cargo-check-benches, check-metadata-hash, cargo-check-each-crate
- tests-linux-stable.yml: test-linux-stable-int, test-linux-stable-runtime-benchmarks, test-linux-stable, test-linux-stable-no-try-runtime
- build-misc.yml: build-runtimes-polkavm
This fixes WASM build failures in container jobs where the wasm32v1-none target is not available by default.
Root cause: CI Docker images don't have wasm32v1-none target installed.
wasm-builder falls back to wasm32-unknown-unknown with -Z build-std=core,alloc
which causes duplicate alloc crate and 'exchange_malloc' lang item error.
Solution: Add 'rustup target add wasm32v1-none' before cargo build steps
in all workflows that build WASM.
Affected workflows:
- checks.yml: cargo-clippy job
- build-publish-images.yml: 11 jobs
- tests-misc.yml: test-node-metrics, test-deterministic-wasm
* 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)
