Subject: [PATCH 1/2] feat: integrate indicatif for terminal progress bar

Replace the manual `\r`-based progress counter with `indicatif` to provide a cleaner, more
reliable progress UI. The previous implementation was visually inconsistent and prone to
terminal corruption under multi-threaded execution.
