Explain process to user

Tell the user "Welcome to the AG Update skill. Let's start by gathering some context on your application"

Read VERSION.md in this skill folder. Fetch the latest: https://raw.githubusercontent.com/ag-grid/skills/main/skills/ag-update/VERSION.md.
Compare as semver:
- If the local version is the same as, or newer than, the fetched version: continue silently.
- If the local version is older and only the patch or minor differs: Prominently tell the user that a new version has been released, show the new and currently installed version, suggest quitting the harness and running npx skills update ag-grid/skills. Ask the user if they'd like to continue with this old skill version, suggesting they type "continue" to do so.
- If the local version is older and the major differs: Prominently tell the user that their current skill version is incompatible and will not work, show the new and currently installed version, tell them to quit the harness and run npx skills update ag-grid/skills before resuming. Stop. The skill invocation is now finished. Regardless of the user response, do not follow any of the other instructions in this file.
