feat: generate dashboard file and config hashtag during init

This change updates the `torch init` command to:
1.  Prompt the user for a Nostr hashtag (defaulting to `${namespace}-agent-lock`).
2.  Explicitly save the `hashtag` to `torch-config.json` under `dashboard.hashtag` for easier editing.
3.  Generate a `TORCH_DASHBOARD.md` file in the installation directory containing a link to the TORCH dashboard with the correct `hashtag`, `namespace`, and `relays` pre-filled.

This improves the onboarding experience by making it easier to find and monitor the agent locks immediately after initialization.
