Research direction
Examine the existing `uv pip tree` implementation in `crates/uv cli/src/commands/pip/tree.rs`. Identify how other commands like `uv pip list` handle JSON output. Implement a ` json` flag that serializes the dependency tree to JSON using serde. Validate the output format against the requirements discussed in the issue comments.
