fix(npm): download binaries during postinstall

The npm package was missing the actual binary download step - users got
wrapper scripts pointing to non-existent binaries.

Changes:
- postinstall.js now downloads correct binary from GitHub releases
- Added vestige.js wrapper for CLI binary
- Exposed both vestige-mcp and vestige commands in package.json
- Updated README with troubleshooting, storage info, CLI docs
- Added .gitignore for downloaded binaries

Fixes fresh install issues where Claude Desktop couldn't attach and
vestige CLI wasn't found.

 ## Features
 
 - **FSRS-6 Algorithm**: State-of-the-art spaced repetition for optimal memory retention
 - **Dual-Strength Memory**: Bjork & Bjork (1992) - Storage + Retrieval strength model
-- **Sleep Consolidation**: Bio-inspired memory optimization cycles
+- **Synaptic Tagging**: Memories become important retroactively (Frey & Morris 1997)
-- **Semantic Search**: Local embeddings for intelligent memory retrieval
+- **Semantic Search**: Local embeddings via nomic-embed-text-v1.5 (768 dimensions)
-- **Local-First**: All data stays on your machine
+- **Local-First**: All data stays on your machine - no cloud, no API costs
 
-## MCP Tools
+## Storage & Memory
 
-| Tool | Description |
+Vestige uses SQLite for storage. Your memories are stored on **disk**, not in RAM.
-|------|-------------|
+
-| `remember` | Store a new memory with importance scoring |
+- **Database limit**: 216TB (SQLite theoretical max)
-| `recall` | Retrieve memories by semantic similarity |
+- **RAM usage**: ~64MB cache (configurable)
-| `search` | Full-text search across all memories |
+- **Typical usage**: 1 million memories ≈ 1-2GB on disk
-| `consolidate` | Trigger memory consolidation (sleep cycle) |
+
-| `get_context` | Get relevant context for current project |
+You'll never run out of space. A heavy user creating 100 memories/day would use ~1.5GB after 10 years.
+
+## Embeddings
+
+On first use, Vestige downloads the nomic-embed-text-v1.5 model (~130MB). This is a one-time download and all subsequent operations are fully offline.
+
+The model is stored in `.fastembed_cache/` in your working directory, or you can set a global location:
+
+```bash
+export FASTEMBED_CACHE_PATH="$HOME/.fastembed_cache"
+```

+
+## Troubleshooting
+
+### "Could not attach to MCP server vestige"
+
+1. Verify binary exists: `which vestige-mcp`
+2. Test directly: `vestige-mcp` (should wait for stdio input)
+3. Check Claude logs: `~/Library/Logs/Claude/` (macOS)
+
+### "vestige: command not found"
+
+Reinstall the package:
+```bash
+npm install -g @vestige/mcp
+```
+
+### Embeddings not downloading
+
+The model downloads on first `ingest` or `search` operation. If Claude can't connect to the MCP server, no memory operations happen and no model downloads.
+
+Fix the MCP connection first, then the model will download automatically.
