ci: publish pkg.pr.new previews on every PR / push#7
Merged
Conversation
Adds a `preview` job (gated on tests passing) that publishes a commit-SHA-pinned preview of the tool via pkg.pr.new and posts a sticky PR comment with an install URL: `npm i https://pkg.pr.new/@juspay/rescript-bindgen@<sha>`. Lets anyone test the exact build of a PR/commit in another project without a real release or npm link. Requires the pkg-pr-new GitHub App on the repo (installed). PUBLISHING.md documents it.
Adds a "Preview builds" section under Install — how to `npm i` a commit-pinned preview (https://pkg.pr.new/@juspay/rescript-bindgen@<sha>) to test an unreleased change, and that previews don't affect the normal latest/beta install.

Adds per-PR/commit preview builds of the tool itself via pkg.pr.new, mirroring blend's #1358 but adapted for this repo (npm, single package, no build step).
What it does
A new
previewjob inci.yml(gated on the smoke + golden tests passing) runsnpx pkg-pr-new publishon every PR and every push tomain. The bot posts a sticky PR comment with an install URL:Why
Right now, testing an unreleased fix means using local source or
npm link. With previews, anyone cannpm ithe exact build of a PR/commit into another project and runnpx rescript-bindgen …— no clone, no link, no waiting for a real release. (This is exactly the gap we hit testing the @types/react fix.)Previews live on pkg.pr.new's domain (not npmjs.org), are commit-pinned and ephemeral, and don't touch
latest/beta.Setup
The pkg-pr-new GitHub App is already installed on the repo (no token to manage).
