[Bug] Version normalization causes false upgrades and branding leaks

[anandgupta42]

Tracking issue for the fixes in #211. The Installation.VERSION constant retained the 'v' prefix from the CI git tag, causing version comparison failures with latest() which returns clean semver. Additionally, several user-facing strings still referenced 'opencode' instead of 'altimate'.
