Agent Skills: lisa-wiki-onboard-me

Onboard a user to the project via its LLM Wiki. Interviews the user about themselves in relation to the project, captures that to project-scoped memory only, then gives a guided tour of what the project is and sample questions they can ask. Use when someone is new to the project or asks to be onboarded. Read-mostly — it does not open PRs or write PII into the wiki.
