chore(pre-deploy): warn about depends_on: service_completed_successfully to use pre-deploy hook instead

This adds 'doc --manual' that generates the manual pages in the current
directory.

This allows for packaging the manual pages in the same way as the
completion, e.g. https://github.com/miekg/unpkg/blob/main/deb/uncloud/debian/rules#L28
(For debian packages local manpages should be included)

+# Developing Uncloud
+
+A short guide on setting up your local development environment.
+
+## Prerequisites
+
+- [mise](https://mise.jdx.dev/) (development environment setup tool)
+- [Docker](https://docs.docker.com/get-docker/) (for running end-to-end tests)
+
+## Setup
+
+Uncloud uses `mise` to install and manage development tools and dependencies. It makes it easy to create reproducible
+development environments on developer machines and CI.
+
+Follow the [Installing Mise](https://mise.jdx.dev/installing-mise.html) guide to get it set up on your machine.
+
+Mark the project as trusted and install all required tools (Go, `protoc`, `golangci-lint`, etc.) by running from the
+project root:
+
+```shell
+mise trust
+mise install
+```
+
+This reads [`mise.toml`](mise.toml) and installs the exact versions of tools specified there. They will be available in
+your `PATH` when you are in the project directory, so you can run `go` or `golangci-lint` directly. The tools won't be
+available outside the project, so they don't interfere with system packages.
+
+## Building
+
+Build the CLI:
+
+```shell
+go build -o uc ./cmd/uncloud
+```
+
+Or build and run the CLI with a single command:
+
+```shell
+go run ./cmd/uncloud --help
+```
+
+The Uncloud daemon (`uncloudd`) only supports Linux, so you need to cross-compile it if you're developing on macOS or
+Windows:
+
+```shell
+GOOS=linux GOARCH=amd64 go build -o uncloudd ./cmd/uncloudd
+```
+
+## Testing
+
+Run all tests (unit and e2e):
+
+```shell
+make test
+```
+
+### End-to-end tests
+
+E2e tests run inside Docker using the [Uncloud-in-Docker](#uncloud-in-docker-ucind) image. Build it first:
+
+```shell
+mise ucind:image
+```
+
+⚠️ NOTE: You need to rebuild the `ucind` image every time you make changes to the daemon code if you want to test them
+in e2e tests.
+
+Then run the tests:
+
+```shell
+make test-e2e
+```
+
+If tests leave leftover containers, clean them up with:
+
+```shell
+make test-clean
+```
+
+### Manual testing on dev machines
+
+After making changes to the daemon code, you may want to test them in your dev cluster. Build and install `uncloudd` on
+one or multiple dev machines over SSH with:
+
+```shell
+mise run dev:install user@host1 user@host2/arm64
+```
+
+It will also restart the `uncloud.service` daemon on those machines to pick up the new version. The host format is
+`[user@]host[/arch]`. The architecture of a machine defaults to `amd64` if not specified.
+
+To stop the daemon and wipe all Uncloud data on the dev machines, run:
+
+```shell
+mise run dev:reset user@host1 user@host2
+```
+
+## Linting and formatting
+
+Lint and format the code:
+
+```shell
+make lint-and-fix
+```
+
+## Code generation
+
+Update the generated Go code for the machine gRPC API after modifying `.proto` files:
+
+```shell
+mise run proto
+```
+
+Regenerate mocks:
+
+```shell
+make mocks
+```
+
+## Uncloud in Docker (UCinD)
+
+The [`ucind`](./cmd/ucind) CLI lets you run Uncloud clusters locally using Docker containers instead of real machines.
+Each cluster machine runs as a Docker container connected to a shared Docker network.
+
+Cluster machines use the `ghcr.io/psviderski/ucind:latest` Docker image by default. It may not always have the
+latest changes to the `uncloudd` daemon code as it's not automatically rebuilt on CI yet.
+
+You can rebuild it locally to pick up the latest changes, including your work in progress, and test them in a UCinD
+cluster:
+
+```shell
+mise ucind:image
+```
+
+Create a cluster with 3 machines:
+
+```shell
+mise ucind cluster create -m 3
+```
+
+This also sets the new cluster as the active context, so you can interact with it using the `uc` CLI right away.
+
+Remove the cluster when you're done:
+
+```shell
+mise ucind cluster rm
+```
+
+Sometimes crashed tests or interrupted runs can leave orphaned containers and networks behind. Clean them all up with:
+
+```shell
+mise ucind:cleanup
+```

+## 🧪 Interactive tutorials
+
+To give you a chance to play with Uncloud without even leaving your browser, we're providing interactive tutorials and playgrounds on the [iximiuz Labs](https://labs.iximiuz.com/) platform.
+
+Available tutorials:
+
+1. [Setting up a new Uncloud cluster](https://labs.iximiuz.com/tutorials/uncloud-create-cluster-ebebf72b) - the tutorial walks you through creating a new cluster with two machines and then deploying a simple web service to it.
+
+You can also launch the [Uncloud playground](https://labs.iximiuz.com/playgrounds/uncloud-cluster-64523f7c) where you can play with an already initialized Uncloud cluster.
