Add runner capability detection and reporting

This change adds automatic detection of runner capabilities including: - OS and architecture - Docker/Podman availability and version - Docker Compose support - Available shells (bash, sh, pwsh, etc.) - Installed development tools (Node, Go, Python, Java, .NET, Rust) - Feature support flags (cache, services, composite actions) - Known limitations (artifact v4 not supported) Capabilities are detected on startup and sent to Gitea via the CapabilitiesJson field in DeclareRequest. This enables AI tools to query runner capabilities before generating workflows. Uses GitCaddy fork of actions-proto-go with capability support. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

This enables AI tools to query runner capabilities before generating workflows.

Max P.	774f316c8b	fix(dockerfile): Pin docker dind images to version 28, as version 29 has breaking changes in the API that are currently causing problems with the `act` fork of Gitea (#769 ) The effect probably does not yet occur in the published versions because the last publication took place before the release of Docker v29.
