Add the release mechanism, mirroring xslint

A tag-triggered release.yml publishes to npm via OIDC trusted publishing (with
provenance) and sets the GitHub release notes from CHANGELOG.md, exactly as in
xslint: @rultor release validates the tag and runs lint + test + coverage, then
pushes the tag that triggers this workflow. Adds scripts/changelog-notes.js,
CHANGELOG.md with the 0.0.1 notes, and the repository field npm provenance
needs. Version stays 0.0.0 and is stamped from the tag at release time.

+# Changelog
+
+All notable changes to this project are documented in this file. The format is
+based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and the
+project follows [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## Unreleased
+
+## 0.0.1
+
+- Initial release. A Language Server Protocol server that wraps
+  [xslint](https://github.com/maxonfjvipon/xslint): live diagnostics as you
+  type over the editor buffer, quick-fixes for the fixable checks, and a
+  fix-all action — all reusing xslint's own `lint` and `fixed` engine, so an
+  editor fix is identical to a command-line `--fix`. Ships with a VS Code
+  extension client, and works in any LSP-capable editor.
