memem-welcomelisted

Force-display the full memem welcome (the brand-new-user view), even if the user has already dismissed it. This is the "re-open walkthrough" handle — it exists so returning users who want the intro again don't have to delete state files manually. **Step 1 — Print the banner:** ``` ███╗ ███╗███████╗███╗ ███╗███████╗███╗ ███╗ ████╗ ████║██╔════╝████╗ ████║██╔════╝████╗ ████║ ██╔████╔██║█████╗ ██╔████╔██║█████╗ ██╔████╔██║ ██║╚██╔╝██║██╔══╝ ██║╚██╔╝██║██╔══╝ ██║╚██╔╝██║ ██║ ╚═╝ ██║███████╗██║ ╚═╝ ██║███████╗██║ ╚═╝ ██║ ╚═╝ ╚═╝╚══════╝╚═╝ ╚═╝╚══════╝╚═╝ ╚═╝ persistent memory for Claude Code ``` **Step 2 — One-sentence pitch:** > memem gives Claude Code persistent memory across sessions. It extracts durable lessons (decisions, conventions, bug fixes, preferences) from your completed sessions into markdown files, then surfaces the relevant ones at the start of each new session. **Step 3 — How it works:** 1. You work normally in Claude Code — nothing to do. 2. Once you opt in via `/memem-mine` or `/memem-mine-history`, the Stop hook fires on every conversation turn and spawns a detached `mine_delta` subprocess. 3. `mine_delta` extracts durable memories from the new turns via Claude Haiku and writes them to `~/obsidian-brain/memem/memories/` — memories appear seconds after each turn ends. No background daemon, no 5-minute wait. 4. Your next session starts with relevant context pre-loaded from memory — no re-explaining the project. **Step 4 —
