Add user_invocable: true to SKILL.md frontmatter

Hey! First off — really appreciate you building this skill. Just installed it and the depth of the coaching system is impressive.

I could be wrong on this, but I noticed the SKILL.md is missing user_invocable: true in the frontmatter, which means it doesn't show up in the Claude Code skills list (the one you see when you type /). Users have to know to talk about interview prep for it to activate automatically.

Adding this one line to the frontmatter seems to fix it:

user_invocable: true

Totally possible this was intentional on your part — just figured I'd flag it in case it wasn't. Thanks again for sharing this!

I like the idea 👍🏻.

I think this can be a useful feature ... I often find myself re-reading the README.md file to see what the options are.

Happy to open a PR for this if it'd be helpful. Looks like a one-line fix.
