Update version to 0.4.1 across all project files

[Copilot]

Summary

This PR updates the version number from 0.4.0 to 0.4.1 consistently across all files in the repository, resolving version inconsistencies that existed in several locations.

Changes Made

Updated version references in the following files:

• config.go - Core application version constant
• config_test.go - Test expectation for version validation
• info_test.go - Test expectation for app info display
• .github/workflows/appimage.yml - AppImage build artifact naming (both build and upload steps)
• snap/snapcraft.yaml - Snap package version (was still at 0.3.4)
• CHANGELOG.md - Added new 0.4.1 release entry

Notes

• The us.tylerc.cycles.yaml flatpak configuration already had the correct version (0.4.1) and did not require changes
• Historical documentation in CHANGELOG.md and OVERHAUL_SUMMARY.md correctly preserves references to previous versions (0.4.0, 0.3.4)

Fixes the version inconsistencies mentioned in the issue, ensuring all active version references throughout the codebase are now synchronized at 0.4.1.
