Verify a change to this VS Code extension end-to-end - which tests to run for which change (unit vs integration tests) and how to launch and exercise the extension manually. Use before committing, when running or checking the extension, when asked to run integration tests, or when launching the Extension Development Host (F5).

Prepare a release - determine the next version from commits, bump package.json, update CHANGELOG.md, and create a release branch. Use when the user asks to prepare, cut, or start a release.

Update CHANGELOG.md from commit history following this repo's Keep a Changelog conventions. Use whenever CHANGELOG.md needs new entries - never edit the changelog ad hoc.
