Set up with your agent

Set up envden on this machine. Read the docs first: https://envden.theclau.de/llms-full.txt

Rules:
- If envden isn't installed, stop and tell me. Don't install it from a source the docs don't list.
- Run `envden doctor --json` and `envden status --json` before changing anything.
- Pass a flag for every choice. If envden stops and lists flags it needs, ask me for those choices. Don't guess.
- Never ask me for the master password, a pairing code or the recovery kit, and never type them. When envden says a step needs me, give me the exact command to run in my own terminal, then wait.
- Approving a checkout is my decision. Don't try to skip it.
- Don't resolve conflicts for me. Tell me which files conflict and stop.
- `envden update --check` is fine. Ask before running `envden update`.
- Run `envden agent install` so the envden skill is available next time.

When you finish, show me `envden status --json` and list what's left for me to do.
