docs: restructure README for 30-second onboarding

README: 1,565 → 196 lines (87% reduction)

New structure:
- Quick Start above the fold (download → connect → test)
- Why Vestige in 5-row table
- Tools reference
- CLAUDE.md trigger words
- Collapsible troubleshooting
- Links to detailed docs

New docs/:
- FAQ.md: 870 lines of community Q&A
- SCIENCE.md: FSRS-6, dual-strength memory, neuroscience
- STORAGE.md: Global, per-project, multi-Claude setup
- CLAUDE-SETUP.md: Full templates for proactive memory
- CONFIGURATION.md: CLI commands, env vars

All content preserved, just reorganized for scannability.

+# Storage Configuration
+
+> Global, per-project, and multi-Claude setups
+
+---
+
+## Database Location
+
+All memories are stored in a **single local SQLite file**:
+
+| Platform | Database Location |
+|----------|------------------|
+| macOS | `~/Library/Application Support/com.vestige.core/vestige.db` |
+| Linux | `~/.local/share/vestige/core/vestige.db` |
+| Windows | `%APPDATA%\vestige\core\vestige.db` |
+
+---
+
+## Storage Modes
+
+### Option 1: Global Memory (Default)
+
+One shared memory for all projects. Good for:
+- Personal preferences that apply everywhere
+- Cross-project learning
+- Simpler setup
+
+```bash
+# Default behavior - no configuration needed
+claude mcp add vestige vestige-mcp -s user
+```
+
+### Option 2: Per-Project Memory
+
+Separate memory per codebase. Good for:
+- Client work (keep memories isolated)
+- Different coding styles per project
+- Team environments
+
+**Claude Code Setup:**
+
+Add to your project's `.claude/settings.local.json`:
+```json
+{
+  "mcpServers": {
+    "vestige": {
+      "command": "vestige-mcp",
+      "args": ["--data-dir", "./.vestige"]
+    }
+  }
+}
+```
+
+This creates `.vestige/vestige.db` in your project root. Add `.vestige/` to `.gitignore`.
+
+**Multiple Named Instances:**
+
+For power users who want both global AND project memory:
+```json
+{
+  "mcpServers": {
+    "vestige-global": {
+      "command": "vestige-mcp"
+    },
+    "vestige-project": {
+      "command": "vestige-mcp",
+      "args": ["--data-dir", "./.vestige"]
+    }
+  }
+}
+```
+
+### Option 3: Multi-Claude Household
+
+For setups with multiple Claude instances (e.g., Claude Desktop + Claude Code, or two personas):
+
+**Shared Memory (Both Claudes share memories):**
+```json
+{
+  "mcpServers": {
+    "vestige": {
+      "command": "vestige-mcp",
+      "args": ["--data-dir", "~/shared-vestige"]
+    }
+  }
+}
+```
+
+**Separate Identities (Each Claude has own memory):**
+
+Claude Desktop config - for "Domovoi":
+```json
+{
+  "mcpServers": {
+    "vestige": {
+      "command": "vestige-mcp",
+      "args": ["--data-dir", "~/vestige-domovoi"]
+    }
+  }
+}
+```
+
+Claude Code config - for "Storm":
+```json
+{
+  "mcpServers": {
+    "vestige": {
+      "command": "vestige-mcp",
+      "args": ["--data-dir", "~/vestige-storm"]
+    }
+  }
+}
+```
+
+---
+
+## Data Safety
+
+**Important:** Vestige stores data locally with no cloud sync, redundancy, or automatic backup.
+
+| Use Case | Risk Level | Recommendation |
+|----------|------------|----------------|
+| AI conversation memory | Low | Acceptable without backup—easily rebuilt |
+| Coding patterns & decisions | Medium | Periodic backups recommended |
+| Sensitive/critical data | High | **Not recommended**—use purpose-built systems |
+
+**Vestige is not designed for:** medical records, financial transactions, legal documents, or any data requiring compliance guarantees.
+
+---
+
+## Backup Options
+
+### Manual (one-time)
+
+```bash
+# macOS
+cp ~/Library/Application\ Support/com.vestige.core/vestige.db ~/vestige-backup.db
+
+# Linux
+cp ~/.local/share/vestige/core/vestige.db ~/vestige-backup.db
+```
+
+### Automated (cron job)
+
+```bash
+# Add to crontab - backs up every hour
+0 * * * * cp ~/Library/Application\ Support/com.vestige.core/vestige.db ~/.vestige-backups/vestige-$(date +\%Y\%m\%d-\%H\%M).db
+```
+
+### System Backups
+
+Just use **Time Machine** (macOS) / **Windows Backup** / **rsync** — they'll catch the file automatically.
+
+> For personal use with Claude? Don't overthink it. The memories aren't that precious.
+
+---
+
+## Direct SQL Access
+
+The database is just SQLite. You can query it directly:
+
+```bash
+sqlite3 ~/Library/Application\ Support/com.vestige.core/vestige.db
+
+# Example queries
+SELECT content, retention_strength FROM knowledge_nodes ORDER BY retention_strength DESC LIMIT 10;
+SELECT content FROM knowledge_nodes WHERE tags LIKE '%identity%';
+SELECT COUNT(*) FROM knowledge_nodes WHERE retention_strength < 0.1;
+```
+
+**Caution**: Don't modify the database while Vestige is running.
