steipete/osc-progress

**Summary:** The `osc-progress` package is a tiny TypeScript helper that emits OSC 9;4 progress sequences so developers can show terminal‑based progress indicators (spinner‑style or deterministic percent updates) in modern terminal emulators such as Ghostty, WezTerm, and Windows Terminal. It provides utilities to start a progress display, control its state, and clean up — making it ideal for CLI tools or utilities that need reliable, cross‑terminal progress feedback without pulling in heavy dependencies.
