PRs now stop after bootstrap + tests. The per-march variant builds,
packaging, and upload-artifact steps reuse the same guard the rolling
'latest' tag/release steps already had, so artifacts are only produced
on push to master (or manual workflow_dispatch).
Replaces the single Linux + single Windows tarball with six self-
contained variants — three µarch levels × two OSes. End users on the
Releases page see them as six individually-downloadable archives:
crafter-build-{linux,windows}-x86_64-{v2,v3,v4}.{tar.gz,zip}
Pick the v-level your CPU supports:
v2: SSE4.2 baseline (every x86_64 since ~2011)
v3: AVX2 + FMA + BMI (Intel Haswell+, AMD Excavator+, ~2013+)
v4: AVX-512 (Skylake-X+, recent server-class)
How: the bootstrap binary stays at v2 because the CI SBC (N5105 / Tremont,
no AVX) can't execute v3 or v4 instructions and would crash before it
could rebuild itself for higher levels. Once bootstrap's done, the same
v2 binary is re-invoked with CRAFTER_BUILD_MARCH overridden per variant
to produce v2/v3/v4 outputs. Same again with --target=x86_64-w64-mingw32
for the Windows variants. ExternalDependency cache keys on (url, target,
march) already so glslang gets built per variant; subsequent CI runs hit
the cache.
Also drops the wrapper zip from workflow artifacts: instead of one
upload-artifact call producing crafter-build.zip containing six archives,
there's now one call per archive. The PR / run page shows six small
downloads named for what they are.
forgejo-release continues to upload release-dir/* as individual assets,
so the Releases page already has the right shape — this just brings the
workflow artifact UX in line.
Bumped the glslang cache key to v2 (one-time invalidation) since the
cache layout now needs space for six glslang builds rather than two.

Setting CRAFTER_BUILD_MARCH=x86-64-v2 made crafter-build emit the
mingw cross-compile to bin/crafter.build-exe-x86_64-w64-mingw32-x86-64-v2/
but the package step still hardcoded -native, causing cp to fail.
Use ${CRAFTER_BUILD_MARCH} in the path so workflow env and packaging
stay in sync.

Two CI fixes from run #276 (got all the way through tests + mingw cross-
compile + packaging, only failed on artifact upload):
march: workflow now sets CRAFTER_BUILD_MARCH=x86-64-v2 / MTUNE=generic;
project.cpp reads both and applies them to the lib + exe Configurations
so the self-rebuild and mingw cross-compile honor the same baseline.
v3 is unusable on the runner — Intel N5105 (Tremont) has no AVX2, so
a v3 bootstrap binary wouldn't even start. v2 (SSE4.2) runs on the SBC
and on every x86_64 CPU since ~2011.
upload-artifact: pinned to v3. v4+ uses a GHES-only API that Forgejo
Actions doesn't implement; the v3 action stays on the older API that
Forgejo supports.

archlinux:latest slim image has no local pacman master key and an
unpopulated upstream keyring, so:
- the archlinux-keyring upgrade fails with "no secret key available to
sign with" because pacman can't sign the keyring it's rewriting
- falling through to -Syu hits the original "unknown trust" errors on
libseccomp and zip
Run pacman-key --init then --populate archlinux before any pacman -S.
This is the documented bootstrap for slim Arch CI containers.

archlinux:latest container ships a snapshot keyring; packages signed by
keys added after the snapshot date fail PGP verification (zip-3.0-13 hit
this with a "signature from Robin Candau is unknown trust" error). Update
the keyring first via pacman -Sy archlinux-keyring, then -Syu the rest.

WASI / wasm32 target support
- Auto-detect /usr/share/wasi-sysroot on Linux when target starts_with("wasm32")
- Skip -march/-mtune for wasm (clang rejects them)
- Apply -fno-exceptions -fno-c++-static-destructors -mllvm -wasm-enable-sjlj
-D_WASI_EMULATED_SIGNAL to wasm builds (compile + std PCM, kept in sync)
- .wasm output extension in expectedOutputFor and link command
- EnableWasiBrowserRuntime(cfg): opt-in helper that drops index.html +
runtime.js next to the .wasm; runtime.js reads window.CRAFTER_WASM_URL
set in the templated index.html so a single shim handles any output name
-r run flag in the CLI: build then exec the artifact (host targets only;
rejects libraries; auto .exe/.wasm extension handling)
CI pipeline (.forgejo/workflows/ci.yaml)
- Triggers: PR/push to master + manual dispatch
- Single arch-latest container job: install deps, bootstrap, self-rebuild,
run tests, cross-compile mingw, package both archives, upload artifacts
- Rolling 'latest' release published only on push/dispatch to master
mingw cross-compile from Linux now works end-to-end:
- ExternalDependency cache key includes target so per-target glslang builds
don't collide; CMAKE_BUILD_TYPE=Release pinned (otherwise glslang appends
'd' to lib names and breaks linking); cross-compile cmake flags
(CMAKE_SYSTEM_NAME=Windows, CMAKE_*_COMPILER_TARGET=...)
- project.cpp accepts --target=<triple>; Linux-only -Wl,--export-dynamic
and -ldl are gated; mingw glslang skips the standalone exe (its libgcc_eh
link pulls pthread which mingw doesn't link by default)
- mingw compile uses -femulated-tls so std::__once_callable etc reference
the same emutls symbols libstdc++ provides
- mingw link auto-adds -lstdc++exp -lpthread
GetCrafterBuildHome() exposed from the Platform module; LoadProject (Linux
+ Windows) now both use it instead of duplicating the resolution.
Examples reorg: hello-world, library, with-module, wasi, tests — each with
its own README. Tests reorg: per-test directory with inner/ fixture, no
shared tests/fixtures/ tree. New Wasi test verifies .wasm magic bytes.
