📝 Walkthrough

Walkthrough

This PR removes styled console output, including colors and decorative icons, across four modules. Spinner templates and status messages are simplified to plain text with em-dash prefixes, and ANSI styling calls are removed throughout.

Changes

Cohort / File(s)	Summary
Spinner and Status Message Styling src/git.rs, src/main.rs, src/pr.rs	Replaced styled progress spinners (e.g., "{spinner:.cyan} ...") with plain templates. Removed colored checkmarks and success indicators, replacing them with em-dash-prefixed plain text messages. Removed console::style imports.
UI Prompt Restructuring src/ui.rs	Reworked all prompts to use plain text without ANSI styling. Simplified prompt menus for uncommitted changes, branch actions, commits, and PR creation. Implemented dynamic prompt text and inline ANSI clear/refresh sequences for live preview updates during editing.

Poem

🐰 Styling stripped with careful care,
Plain text messages float through air,
No colors now, no icons bright,
Just simple text—crisp and light!
