Add tarot command and MCP tool for Major Arcana draws#7
Merged
Conversation
Implements the `tryluck tarot` CLI command and a corresponding MCP tool
that draws cards from the 22 Major Arcana without replacement, with
upright/reversed orientation for each card.
- Add `src/commands/tarot.rs` with card data, `draw()`, and `run()`
- CLI: `tryluck tarot [N]` prints proper-case names by default (e.g. "The Fool");
reversed cards are shown as reversed characters (e.g. "looF ehT")
- CLI: `--json` outputs a JSON array of `{card, orientation}` objects,
defaulting to snake_case names for AI/tokenizer friendliness
- CLI: `--case snake|proper` overrides the name format in any output mode
- MCP: new `tarot` tool returning the same structured JSON (snake_case default)
- Add `serde_json` dependency for CLI JSON serialization
