feat(packaging): ship crafter-build as a Flatpak with its own toolchain packaging/flatpak/ holds the manifest for net.catcrafts.CrafterBuild and its side files. The runtime is the Freedesktop Sdk, not the Platform: a build tool needs glibc's headers and crt objects, gcc's libgcc_s, cmake, ninja, git and python at run time. Everything compiler-shaped is ours under /app, built from one LLVM 22.1.8 source tree: clang, lld, libclang, libc++ with its std module, compiler-rt for the host and for wasm32, the WASI sysroot (wasi-sdk 34 in sysroot-only mode, driven by the clang just built) and wasmtime for running the result. One tree means the modules crafter-build builds and the compiler that consumes them cannot drift apart, and the toolchain resolver finds all of it beside the executable with no configuration. The crafter-build module runs the bootstrap, the self-host build and the test suite inside the sandbox, so a Flatpak that installs has passed the suite with the toolchain it ships. CRAFTER_BUILD_MARCH is x86-64-v2 for the shipped binary; user projects keep -march=native. WasmHelloRuns compiles a fixture for wasm32-wasip1 and runs it under wasmtime. The existing wasm tests only inspect generated files, so this is the one that proves the sysroot, the std module for wasm and wasm-ld work together; it skips where the sysroot or wasmtime is missing.
