feat: initial implementation of anki-mcp MCP server

Implements a FastMCP server that wraps AnkiConnect (localhost:8765)
to expose Anki flashcard management as Claude MCP tools.

Tools provided:
- list_decks: list all deck names
- create_deck: create nested decks (:: separator)
- add_card: add Basic flashcard with optional tags
- get_due_cards: fetch today's due cards with optional deck filter
- update_card: edit front/back of existing note
- update_deck: rename deck (move-cards approach)
