color escape codes are left open

Current evaluation

Snapcraft's snapping progress spinner emits a green ANSI color code without a matching reset, so interrupting the build leaves the terminal green. Open since 2017 with zero comments; spinner logic now lives in the craft-cli dependency, so current behavior is unverified.

Suggested action: needs triage

Reason: Zero comments, no labels beyond 'ui', and no maintainer interaction in ~8.5 years (last activity 3084 days ago), so it has never been triaged. The spinner code has since moved to the craft-cli dependency (AGENTS.md maps 'Terminal output, progress reporting' to craft-cli), so a maintainer needs to verify whether the reset code is still missing before closing or fixing. A related report (#1692754, 'snapcraft turns the console text green') was closed as abandoned, but this one is distinct (interrupt during snapping vs. after completion).

Impact: 20 Quick Win: 15.0 Staleness: 85 Complexity: 25 Confidence: 55 Support Request: 5

Issue body

When snapcraft is doing the actual snapping step and the progress spinner is animating, the green color terminal escape codes are left "open". That is, there is a "begin green color" escape code, but no "end color" code. The "end color" code isn't added until after snapping completes. This has a problem: if you stop, interrupt, or kill snapcraft during the snapping process, your terminal stays green (including your prompt, anything you type, and the output of all commands) until you somehow insert the correct escape code to stop color. During the snap step, snapcraft should add the "end color" escape code to the end of every print statement so that, no matter when in the process it gets interrupted, the color is left turned off after snapcraft runs.

Same terminal-color-reset symptom reported earlier; closed without resolution due to inactivity, so no fix evidence there.
