Research direction
The error occurs when parsing the output of `gh pr status`. rtk likely uses serde to deserialize the JSON response from the GitHub CLI. The `currentBranch` field was added in a newer version of gh, causing deserialization to fail because the corresponding Rust struct either lacks this field or has `deny unknown fields` enabled. Check the file handling `pr status` (e.g., `src/commands/gh.rs` or similar). The fix could be adding `currentBranch` to the struct or using `#[serde(deny unknown fields)]` to ignore unknown fields. First, confirm which struct is used and whether the tool uses `gh`'s JSON output directly.
