v0.1.16 — install UX polish: zero-credential demo, marketplaces, badges

Three improvements that close the install-friction gap versus other shipped MCP servers — without giving up amnesic's conceptual simplicity.

✨ amnesic init --demo — zero-credential trial

A new _demo.py builds a tiny self-contained SQLite e-commerce database (20 customers, 30 products, 100 orders, 232 line items, a full FK graph, and an integer status enum that's perfect for db_annotate). amnesic init --demo creates the DB, adds a [connections.demo] block to connections.toml, and is idempotent — re-running refreshes the data without duplicating config.

A curious visitor now goes from pipx install amnesic to actively using every tool in under 60 seconds — no database credentials required.

📦 Install UX

• Badges row (PyPI version, downloads, Python, license, MCP Registry, stars)
• "Works with" compatibility line listing 6 named clients + the MCP standard
• "Available on" row linking the Official MCP Registry and the new Claude Code plugin marketplace
• Claude Code section now leads with one-line install:
  /plugin marketplace add SurajKGoyal/amnesic-marketplace

🔌 Claude Code plugin marketplace

amnesic is now installable as a Claude Code plugin via SurajKGoyal/amnesic-marketplace — no manual mcp.json editing.

Install: pipx install amnesic → amnesic init (or amnesic init --demo)
