AIGX 1.3.2 — npm ecosystem published (@aigx/cli)

AIGX is on npm. First publish of the package ecosystem. The CLI ships as @aigx/cli — npm reserves
the bare aigx name (typosquat filter), so it's scoped under the aigx org. The installed command is
still aigx.

Live on npm

Package	Version	Use
create-aigx	1.3.1	npm create aigx · npx create-aigx
@aigx/cli	1.3.1	npm i -g @aigx/cli (→ aigx) · npx @aigx/cli
@aigx/parser	1.2.0	npm i @aigx/parser
@aigx/lint	1.2.0	npm i @aigx/lint

Fixed

• Every npx aigx / npm i -g aigx reference updated to @aigx/cli (scaffolded CI, create-aigx output,
  docs, release harness, meta-genome). pip install aigx / cargo install aigx are unchanged — those
  packages are named aigx.

Still pending

• PyPI (aigx) and crates.io (aigx) — names reserved/available; publish needs those tokens.
• The conformance CI workflow still needs a workflow-scoped push.
