wumbOS Shell v0.1.0-alpha.2

wumbOS Shell v0.1.0-alpha.2 is a repository-hardening release. The shell runtime is unchanged from v0.1.0-alpha.1.

Changes:

• Add a public bug-report issue template.
• Document the maintainer release process.
• Update canonical repository references to WumboLabs/wumbo-quickshell.
• Add path-scoped GitHub Actions testing for the optional OMP integration, with organization-policy-compliant full-SHA action pins.

Support boundaries and known limitations are unchanged from v0.1.0-alpha.1.

This is an early public alpha. Configuration structure, module APIs, integration contracts, and supported environments may change between alpha releases.

GitHub-generated source archives remain sufficient for this release.
