fix: use ASCII arrow for consistent terminal rendering

[BYK]

Summary

Replace Unicode arrow → (U+2192) with ASCII -> in user-facing output to fix rendering issues on certain terminals and fonts.

Problem

The Unicode RIGHTWARDS ARROW has East Asian Width "Ambiguous", causing some terminals/fonts (e.g., Iosevka) to render it as 2 cells while advancing the cursor by only 1. This visually "eats" the following space character.

Before: Update available: 0.0.0-dev →0.6.0 (space missing after arrow)
After: Update available: 0.0.0-dev -> 0.6.0
