Add just bump task to bump version and create tag automatically, fixes #54

[github-actions]

Script Analysis

• The changes introduce a new version bumping utility (bump-ver.nu) with proper version format validation
• Added version parameter to release fetching functions to ensure specific version downloads
• Improved structured data handling in meta.json (changed revision from string to number)
• Added proper error handling and validation in version bumping process
• Using string interpolation for version/subcommand parameters rather than string concatenation

Security Review

• ❗ The signing key is being handled directly from environment without sanitization (line 52/95 in publish.yml)
• ⚠️ Temporary GPG key file is created but no explicit permissions are set (potential race condition)
• The git operations in bump-ver.nu perform direct branch operations without verification of remote state

Optimization Suggestions

• Replace direct file open (open meta.json) with structured input parsing in bump-ver.nu
• Consider parallelizing the architecture-specific release operations in publish.yml
• Add version caching to avoid repeated meta.json parsing in workflow steps
• Use par-each for multiple architecture handling where possible
