Port faiss's linux-riscv64-DD-cmake job (build-pull-request.yml) so PRs get riscv64 coverage without native hardware: - .github/workflows/08-linux-riscv64-rvv-cross.yml: cross-compile with gcc-14-riscv64-linux-gnu using faiss's proven multiarch apt setup (minus libopenblas-dev/libgomp1: no BLAS, ENABLE_OPENMP=OFF), then build and run the whole ailego unit test suite (61 targets) under qemu-user-static with -cpu rv64,v=true,zihintpause=true. - cmake/toolchains/riscv64-linux-gnu.cmake: riscv64-linux-gnu toolchain file ported from faiss, with overridable compiler names. - .github/workflows/01-ci-pipeline.yml: wire the new workflow into the main pipeline. - .github/workflows/10-cmake-subproject-integration.yml: renumbered from 08 to free the slot (standalone nightly, no references by filename). The job passes -DENABLE_RISCV64/-DENABLE_RISCV_VECTOR/ -DENABLE_RISCV_ZIHINTPAUSE; until the RISC-V platform support lands on main these are unused warnings and the job runs as a plain rv64gc cross-compile smoke test.

Ubuntu 24.04 ships qemu-user-static 8.2, which does not emulate the riscv_hwprobe syscall (emulation added in qemu 9.2, reporting V and ZVFH from the -cpu config), so the hwprobe-based CpuFeatures detection would always report false once the RISC-V platform support lands. Install the newest static qemu build from the Ubuntu package pool (currently 9.2.1), enable ENABLE_RISCV_ZVFH, and run the tests with -cpu rv64,v=true,zvfh=true,zihintpause=true.
