Set up Oz automations

Create the Oz environment and schedules that run enrich-notes-loop-cloud nightly and refresh-wiki-cloud weekly against the user's Obsidian Sync vault.

0. Prerequisites

Check whether the Oz platform skill is installed — it teaches the oz CLI. If it's absent, install it:

npx skills add warpdotdev/oz-agent-skill

Read that skill before running any oz commands.

Then gather from the user:

• Obsidian Sync vault name — e.g. Main. They need an Obsidian Sync vault pointed at their notes directory, and the headless CLI auth token for it.
• Schedule times — default to nightly enrichment and weekly wiki refresh if they have no preference.

The skills are pulled straight from bholmesdev/llm-knowledge-base-skills — no repo of their own needed. Only ask about a repo if the user says they've forked the skills to tweak them; then substitute their owner/name everywhere bholmesdev/llm-knowledge-base-skills appears below.
