Warn when shared config file has uncommitted changes

[jcleira]

Summary

After partio enable or partio configure modifies .partio/settings.json, print a hint reminding the user to commit the file so that team members share the same configuration.

Why

When users configure team-shared settings (like checkpoint strategy or agent type), forgetting to commit .partio/settings.json means teammates won't pick up those settings. This is especially easy to miss because the file is created/modified by CLI commands rather than edited by hand. A simple hint at the right moment prevents configuration drift across the team.

Source

• Origin: fix: hint to commit settings.json when using checkpoint remote entireio/cli#861 (hint to commit settings.json when using checkpoint remote)
• Detected from: entireio-cli-pulls

Target Repos

• cli

Acceptance Criteria

• After partio enable or partio configure modifies .partio/settings.json, a hint is printed reminding the user to commit the file if it contains team-shared settings
• The hint only appears when .partio/settings.json has uncommitted changes (not when it is already tracked and clean)
• The hint is suppressed in non-interactive contexts (e.g., CI) or when stdout is not a terminal
• A test verifies the hint appears after a config modification when the file is untracked
• A test verifies the hint does not appear when the file is already committed and unchanged

Context Hints

• cli/cmd/partio/
• cli/internal/config/
