oxicode-cli 0.77.0

// oxicode-cli/src/tui_vt/issues_panel/form.rs
//! Pure helpers for the Create/Edit form (Task 8).
//!
//! `cycle_priority` and `parse_labels` have no interaction with `TextArea`,
//! `FileIssueStore`, or any TUI state — they're pure functions on `Priority`
//! and `&str`, so each gets a focused unit test below. Keeping them out of
//! `mod.rs`/`input.rs` means the tests run instantly and without a
//! `parking_lot::Mutex` plumbing.
