Add the pi package, the Pi coding agent from pi.dev (npm @earendil-works/pi-coding-agent), version 0.84.2.

Pi is a minimal terminal coding harness. It is an npm package, so it is installed from the registry rather than built from the GitHub monorepo, whose build needs the tsgo native TypeScript compiler and a multi-package workspace. This matches the existing npm CLI packages here, with one difference: the tarball is pinned as a Source by sha256 (like cf), and the tarball ships an npm-shrinkwrap.json that locks the transitive dependency tree. The build is reproducible: two --no-cache builds produce identical content-addressed output.

File Purpose
packages/pi/build.ncl Build spec: sha256-pinned registry tarball Source, node + coreutils runtime deps, dns/internet needs, source_provenance = earendil-works/pi
packages/pi/build.sh Installs the pinned tarball into usr/libexec/pi, symlinks usr/bin/pi

Verification:

  • mip check --packages pi passes
  • mip package build pi builds successfully; two --no-cache builds give byte-identical output

- Around line 17-21: Add a pinned Source dependency to build_deps alongside the
existing Local and package entries, including the npm tarball URL and its SHA256
digest. Update the npm installation flow to consume the pinned tarball and
locked dependency graph rather than resolving package content or transitive
dependencies dynamically from the network.

Install the sha256-pinned npm tarball instead of resolving
name@version at build time. The tarball ships npm-shrinkwrap.json,
which locks the transitive dependency tree; two --no-cache builds
produce identical content-addressed output. Addresses PR review.
