- CI: macOS on Apple Silicon and Intel (macos-15, macos-15-intel); a tag v* attaches every package
(Linux x64/ARM64, macOS ARM64/x64, Windows x64, the VS Code extension) to its release
- vectors: fma is llvm.fmuladd (llvm.fma was a libm call per lane without FMA hardware: 3.5x slower)
- examples/simd.fch: a dot product eight at a time, timed against the plain loop
- README and the English guides: installing on Linux, macOS and Windows; vectors (SIMD); --cpu;
-g is DWARF on Windows too (lldb from llvm-mingw); no more mention of the C++ compiler
- comments left from the C++ compiler (src/target.cpp, src/codegen.cpp, "never frees") brought up to date

- a static inline function in a header is called through a pointer a small C file keeps
(void *finch_inl_f = &f), built with the program's include folders and cached
- --shared on macOS links with -undefined dynamic_lookup, as a .so does on Linux
- "unable to find library -lx" (lld, MinGW) gives the library-not-found advice
- the language server test shows the index records when alias completion fails

- finch.toml: name, entry, paths, include, links, libdirs, cflags, ldflags, and [target.windows] etc.;
finch run / build / test with no file use its entry
- import thread: spawn, join, mutex, cpus; atomic_add/sub/load/store/swap/cas built in
- finch fmt [--check]: indentation by { }, trailing spaces, empty lines; also as LSP formatting
- link "x.cpp" (or in finch.toml): built with the C++ compiler, which then links (FINCH_CXX)
- #define RAYWHITE (Color){ 245, 245, 245, 255 } imports as a Color
- push(body) where push takes ptr[Body]: the same as push(addr(body))
- --target android (NDK clang from ANDROID_NDK_HOME, -llog)

Windows: the compiler made from bootstrap/windows-x86_64.ll runs under Wine, compiles itself to the same IR, builds an
exe of itself, and every test program passes through it. It needed: Windows-sized unsigned long for libclang's unsaved
file, no 'cross' when Windows builds for Windows, --target passed to libclang (libclang.dll assumes MSVC), the MinGW
triple always in the IR, FINCH_LDFLAGS, .exe names and FINCH_LLVM_INCLUDE in bootstrap/build.sh, winseed.sh/winbuild.sh.
macOS: seeds for arm64 and x86-64 made with the 11.3 SDK; IR is accepted by clang, nothing has run on a Mac yet.
CI gets a windows and a macos job. UNTESTED on real Windows/macOS runners.

src/embedded.fch (made by tools/pack.fch, checked by tests/run.sh) holds runtime/finch_rt.c and std/; when they aren't
beside the binary they're written to the cache folder once. All the sh/cmd specifics of the driver (quoting, temp dir,
mkdir, rm, mv, null device, path separator, cache dir, binary stdio) moved into host.fch / host_windows.fch.

boot/ is src/ now. The C++ compiler and CMake are gone from this branch (they are on before-bootstrap).
bootstrap/build.sh builds the compiler from bootstrap/<system>.ll -- the compiler's own LLVM IR -- then builds
it with itself and checks the two come out identical. bootstrap/build.sh seed writes the seed anew.
The driver is complete: the runtime is compiled once and kept in ~/.cache/finch; a program's own C files,
.o and .a files and frameworks link along; a linker failure is read and answered with link "lib" or the
library that is missing. The old tests/fail diagnostics are all in again (a missing import, a str compared with
null, 'write just the library's name', a map key that is a float, non-ASCII names, ...).
tests/run.sh is the one test runner: programs, refusals, -g builds and the shared library. 106 passed.
