Fixes #1824 — prebuild-install failing on Node 22.14.0 due to
N-API version string comparison bug in napi-build-utils < 2.0.0.

Dependencies:
- prebuild-install: ^7.1.1 -> ^7.1.3 (fixes N-API version detection)
- prebuild: 12.1.0 -> 13.0.1
- tar: ^6.1.11 -> ^7.5.10 (fixes 6 HIGH CVEs)
- node-addon-api: ^7.0.0 -> ^8.0.0
- node-gyp: 8.x -> 12.x (peer + optional)
- Added engines field: node >=20.17.0
- Added yarn.lock

CI:
- Test matrix: Node 20, 22, 24 (all current LTS lines)
- ubuntu-20.04 -> ubuntu-24.04, alpine3.15 -> alpine3.20
- Replaced macos-m1 self-hosted with macos-latest (now ARM64)
- Dropped win32-ia32 (Node 24 no longer ships 32-bit Windows)
- Excluded macos x64 + Node 20 (Rosetta 2 async hooks bug)
- Removed pip install setuptools workaround
- Updated actions (checkout v6, setup-node v6, upload-artifact v7,
  setup-qemu-action v4, setup-buildx-action v4)
- Sanitised artifact names to avoid slashes from platform targets
- Dockerfile: Node 18 -> 24, bullseye -> bookworm

Two years of upstream improvements including bug fixes, performance
enhancements, and security hardening.

The extract script now removes the VERSION file that SQLite >= 3.49
ships, which conflicts with the C++20 <version> header on
case-insensitive filesystems (macOS/Windows).

- gcc-preinclude.h: include <unistd.h> with _GNU_SOURCE active to
  provide syscall() on musl (fixes GCC 13 atomic_wait.h bug); use
  __GLIBC__ instead of __USE_GNU to guard glibc symbol versioning
- CI: linux-arm64 glibc builds now use native ubuntu-24.04-arm runners
  instead of QEMU emulation (much faster)
- CI: QEMU/Docker retained only for Alpine/musl builds (renamed to
  build-musl)
