Add Fedora/RPM packaging support

[Copilot]

Adds RPM packaging to complement existing Debian package distribution, enabling installation on Fedora, RHEL, and CentOS systems.

Changes

• RPM spec file (fedora-package/SPECS/numberguessinggame.spec): Package definition with java-1.8.0-openjdk-headless dependency, installs JAR to /usr/share/games/numberguessinggame/ and wrapper script to /usr/bin/

• Build script (package-rpm.sh): Automated RPM build using rpmbuild, mirrors existing package-deb.sh workflow

• CI/CD: GitHub Actions release workflow now builds and uploads RPM alongside existing DEB package

• Documentation: Installation instructions for dnf/yum package managers

Installation

sudo dnf install ./numberguessinggame-1.0.0-1.noarch.rpm
numberguessinggame

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

The download URL includes a hardcoded version "1.0.0-1" in the filename (numberguessinggame-1.0.0-1.noarch.rpm), but uses a placeholder 0.x.y for the release tag. This is inconsistent with the DEB instructions (line 22) which only use placeholders. For consistency and to avoid confusion, consider using a placeholder pattern like numberguessinggame-*.rpm or numberguessinggame-1.0.0-1.noarch.rpm with a matching release tag placeholder.

The dependency java-1.8.0-openjdk-headless is very specific and may not be available on all RPM-based distributions. Consider using a more flexible requirement like Requires: java-headless >= 1:1.8.0 or Requires: jre-headless >= 1.8.0 to allow any Java 8+ JRE implementation, similar to how the Debian package uses default-jre | java8-runtime.

Suggested change

	Requires: java-1.8.0-openjdk-headless
	Requires: java-headless >= 1:1.8.0
