Pi-Bolt 0.8.1

Pi-Bolt 0.8.1 runs Pi 1.1.0 on Linux x86-64, macOS on Apple silicon and Windows x64. pi-fff works on the default build, and
installing with npm or Bun is easier.

Extensions

• pi-fff works without the JIT. On the default build, pi-fff stopped at "FFF init failed: bun:ffi requires the JIT". It now
  uses its Node.js backend there (the same native search library), with nothing to set up; the -jit build uses its Bun backend
  as before.

Install

• npm and Bun: npm install -g --allow-scripts=pi-bolt pi-bolt and bun add -g --trust pi-bolt. Both package managers now
  ask before running a package's install script, which on Windows puts the executable in place.
• When a build is not on npm yet, the installers say "not available from npm; downloading from GitHub instead", rather than
  that the download failed.

Benchmarks

• 0.8.0 measured on Linux and macOS against Pi 1.1.0 on Bun and Node, and against PiG and oh-my-pi in the same runs
  (docs/BENCHMARKS.md). The site shows them too.

Installer

• install.sh refuses checksums that say they are another release's, as install.ps1 does: an older release, signed all the
  same, served as a newer one, is no longer installed as the newer.

Engine

• On Windows: an idle keep-alive connection is aged on a clock nobody sets (GetTickCount64), as on Linux and macOS since 0.7.3.
• The writer of the prebuilt heap no longer stops at a pair of numbers that reads like an address of the builder's own memory;
  a word that could be a pointer there still stops it.

Corrections to earlier notes

• 0.7.1 to 0.7.3 said the installer detects Linux or macOS: it is install.sh for those, and install.ps1 for Windows.
• 0.7.1 said git sources are passed with --end-of-options. They are refused when the repository or ref starts with -, which
  works with every git version.

Install

curl -fsSL https://pi-bolt.opensec.in/install.sh | sh

powershell -c "irm https://pi-bolt.opensec.in/install.ps1 | iex"

or pi-bolt update, or npm install -g --allow-scripts=pi-bolt pi-bolt, or bun add -g --trust pi-bolt.

The runtimes

The engine changed (Windows, and 0.7.3's and 0.7.4's changes merged with it), so the runtimes of this release were built by
hand (RELEASING.md). From the engine trees that patches/webkit.patch and
patches/bun.patch make on the pinned sources (git rev-parse HEAD^{tree}): WebKit f527504e0d1d9f14c73b7aab4682fe44972507fa,
Bun 2c4f4980f78e0986a324aa46f648ce05542d9369.

A runtime is not yet built bit for bit the same twice, so these are what was built, not what anyone would get.
