v0.8.0

This release introduces build & push capabilities for Compose deployments, enables [passive health checks](https://caddyserver.com/docs/caddyfile/directives/reverse_proxy#passive-health-checks) for upstreams in Caddy reverse proxy, minor bug fixes and improvements.

We also launched:
* [Uncloud Documentation](https://docs.uncloud.run/)
* [Discord server](https://discord.gg/eR35KQJhPu)

## New features

### Initial build & push support (still experimenting) ✨

* New `uc build` command to build service images from `Dockerfile` and `build:` configuration in Compose files
* Integrated build step in `uc deploy` automatically builds and pushes an image to the registry specified in `image:` before deployment
* Use `--no-build` flag to skip building when deploying

### Caddy reverse proxy improvements

* Enabled [passive health checks](https://caddyserver.com/docs/caddyfile/directives/reverse_proxy#passive-health-checks) to automatically detect unhealthy upstreams
* Added automatic retry logic (3 retries) for failed requests to gracefully handle temporary unavailable upstreams
* Logging enabled by default for better observability

## Documentation
* Launched a new documentation website at [docs.uncloud.run](https://docs.uncloud.run/) with a [Getting started](https://docs.uncloud.run/category/getting-started) guide.
* Documentation itself is deployed using Uncloud across multiple machines (dogfooding FTW!) See the [`compose.yaml`](https://github.com/psviderski/uncloud/blob/main/docs/compose.yaml) file if curious.

## User experience

* Default SSH key path is now set to `~/.ssh/id_ed25519`
* Added `m` alias for the `machine` command

## Bug Fixes

* Fixed Caddy deployment after adding new machine by using cluster client instead of machine client (#65)

## Testing & CI

* Added GitHub Actions workflow for automated Go tests
* Enhanced e2e tests with build & push verification

## Contributors
Thanks to @tonyo for the build & push RFC and implementation, test improvements, and the make `install-dev` helper!
