Build and publish RPM packages for Fedora using rpkg and official
rust-packaging macros. GPG sign packages with Ed25519 repository key
and deploy to Forgejo package registry.
Package organisation works around Forgejo's one-file-per-version limit:
- Binary packages: base group (stable/dev/branch-name)
- Debug packages: GROUP-debug
- Source packages: GROUP-src
Workflow triggers on pushes to relevant paths and version tags (v*).
Tagged releases use clean version numbers (v1.2.3 becomes 1.2.3-1)
while branch builds use git SHA versioning.
Include GPG public key for package verification and documentation
for RPM repository configuration and installation methods.
The Fedora RPM packaging files added in PR #950 weren't passing pre-commit
checks, causing CI failures for any branches rebased after that merge. This
applies prek linting fixes (typo correction, trailing whitespace removal,
and EOF newline) to ensure CI passes for all contributors.
