refactor: move act/model and act/exprparser to actions-proto-go

Gitea needs the workflow model and the expression evaluator to parse
workflows and to build the task payload this runner consumes, so it had
to depend on gitea.com/gitea/runner for it. Both packages now live in
gitea.dev/actions-proto-go, the module both sides already share, and this
repository consumes them from there.

The GithubContext helpers that need a git checkout on disk (SetRef,
SetSha and SetRepositoryAndOwner) are not moved: they are runner only and
would drag a git client and the act context logger into the shared
module. They become functions of the new act/ghcontext package, together
with their tests.

act/common.CartesianProduct moved to the shared model package as well,
act/model was its only user. act/model/testdata/container-volumes is now
act/runner/testdata/container-volumes, its only user is runner_test.go.

The x-runner-uuid and x-runner-token header names come from
actions-proto-go too, so the runner and Gitea cannot drift apart.

 > **Note:** A runner that only exposes `host` labels still needs access to a Docker daemon (e.g. a mounted `/var/run/docker.sock`) whenever a job uses a `docker://` action or a service container. `host` labels only change where the job's own steps run; container-based steps and actions are still executed with Docker.
 
+#### Proxy
+
+Set these variables in the runner's environment, with systemd `Environment=`, `docker run -e`, or Kubernetes `env:`:
+
+```sh
+http_proxy=http://proxy.example:3128
+https_proxy=http://proxy.example:3128
+no_proxy=gitea.internal,.example.local
+```
+
+The runner uses them for its own requests and gives them to every job, in lower and upper case.
+
+These hosts are added to `no_proxy` for jobs, so they are always reached directly:
+
+- the cache server
+- `localhost`, `127.0.0.1` and `::1`
+- the job's service containers
+- the Docker daemon, when it is reached over `tcp://`
+
+Gitea is not added. Add it to `no_proxy` yourself if it should be reached directly.
+
+To change a value for one job, set it in a step's `env:` or in the job's `container.env`. Setting it at workflow or job level has no effect. To change it for the whole runner, set it in `runner.envs`. A `no_proxy` set there is added to the list above instead of replacing it.
+
+Images are pulled by the Docker daemon, which needs its own proxy setting. In the `dind` images the daemon runs in the same container and reads the variables above. For any other daemon, see [the Docker documentation](https://docs.docker.com/engine/daemon/proxy/). The runner logs a warning at startup if it has a proxy and the daemon does not.
+
+Dockerfile actions are built with these variables as build arguments, so their `RUN` steps can reach the network.
+
+A password in a proxy URL is hidden in job logs. Any step can still read it, because the step is given the proxy URL in its environment.
+
 #### Caching (`actions/cache`)
 
 Each runner starts its own cache server automatically. Cache entries are local to that runner — runners do not share a cache by default.
 
+**Cache service v2**
+
+`actions/cache@v4.2` and later can use the *cache service v2* API. The runner serves it from the same store as v1, on by default, and it works with `external_server`. Turn it off with:
+
+```yaml
+cache:
+  v2: false
+```
+
+Those actions refuse any host they do not take for GitHub. Rather than misreport the server URL, the runner edits that check out of the action's own bundle and keeps the untouched copy beside it; a bundle it does not recognise is left alone and keeps to v1. The same edit lets the stock `actions/upload-artifact` and `actions/download-artifact` work from `v4.4.0` on, without the `gitea-upload-artifact` fork.

+#### Job hooks (`runner.hooks.job_started`, `runner.hooks.job_completed`)
+
+Optional scripts that run **inside the job environment** (the job container, or the host in host mode), before the job's first step and after its last one. They are the equivalent of GitHub's `ACTIONS_RUNNER_HOOK_JOB_STARTED` / `ACTIONS_RUNNER_HOOK_JOB_COMPLETED`, which are read when the settings are unset.
+
+Because they run where the steps run and see the job's environment, they are the place for per-job setup no workflow should have to carry: registry logins, mirror configuration, or masking runner-wide secrets with `::add-mask::`. Their output is part of the job log and is scanned for workflow commands, and they can export to the job through `$GITHUB_ENV` and `$GITHUB_PATH`.
+
+Both hooks are synchronous and block the job while they run. Either one exiting non-zero fails the job, and there is no per-hook timeout.
+
+See **[docs/job-hooks.md](docs/job-hooks.md)** for the execution order, environment, and platform notes.

+# Job hooks
+
+Job hooks are operator-provided scripts that run **inside the job environment**, before the job's first step and after its last one. They are the equivalent of GitHub's [job hooks](https://docs.github.com/en/actions/how-tos/manage-runners/self-hosted-runners/run-scripts) and are configured under `runner.hooks` in the runner YAML config (see [config.example.yaml](../internal/pkg/config/config.example.yaml)):
+
+```yaml
+runner:
+  hooks:
+    job_started: /hooks/started.sh
+    job_completed: /hooks/completed.sh
+```
+
+| Setting | Runs |
+| --- | --- |
+| `runner.hooks.job_started` | Before the job's first step, before any action is downloaded |
+| `runner.hooks.job_completed` | After the job's last post step, while the job environment is still up |
+
+`ACTIONS_RUNNER_HOOK_JOB_STARTED` and `ACTIONS_RUNNER_HOOK_JOB_COMPLETED` are read from the runner's environment (`runner.envs`, `runner.env_file`) when the settings are unset, so a configuration carried over from actions/runner keeps working. The settings take precedence. A workflow cannot point the runner at a different hook: the variables are only read from the runner's own environment, never from the job's.
+
+Both hooks are **synchronous** and block the job while they run, and a non-zero exit from either one fails the job. There is no `continue-on-error` and no per-hook timeout — the job's own `runner.timeout` is the only bound. The operator is responsible for the hook's resilience; run anything long in the background from within the hook.
+
+## Where they run
+
+The hooks run in the same place as the job's steps: inside the job container, or on the host in host mode. The paths are resolved *there*, so the script has to exist in the job image or on the host — a path that only exists on the runner host is not visible to a containerized job. For host-wide cleanup that runs after the job environment is gone, use the [post-task script](post-task-script.md) instead.
+
+> This is a deliberate difference from actions/runner, which runs its job hooks on the host, outside any container the job declares. Running them where the steps run is what lets a hook prepare the environment the steps actually see.
+
+The script is run according to its extension:
+
+| Extension | Command |
+| --- | --- |
+| `.sh` | `bash -e <path>` |
+| `.ps1` | `pwsh -command . '<path>'` |
+| anything else | the file itself, which needs its own shebang and executable bit |
+
+As on GitHub, the shell flags applied to `run:` steps are **not** applied to a hook — set `pipefail` or anything else you want inside the script.
+
+### Docker-in-Docker and Docker-out-of-Docker
+
+The hook is executed and its files are exchanged over the Docker API, addressed by container ID, so no path is translated between the runner and the daemon. Both setups work unchanged, but they differ in where the hook file has to be:
+
+- **DinD** — the daemon has its own filesystem. Bake the hook into the job image; a path from the runner's filesystem is not visible to it.
+- **DooD** — the job container is created by the host's daemon, so a bind mount in `container.options` is resolved against the **host**, not against the runner container. Either bake the hook into the job image, or mount a host directory and add it to `container.valid_volumes`.
+
+A hook path that does not exist inside the job environment fails the job with `No such file or directory`, naming the path.
+
+## Environment
+
+A hook sees the job's environment: the workflow, job and `container:` `env:`, the runner's `envs`, and the `GITHUB_*` context variables, with the same masking applied to its output as to a step's. The step-specific ones (`GITHUB_ACTION`, `GITHUB_OUTPUT`, `GITHUB_STATE`) are not set — a hook is not a step, so `::save-state::` and `::set-output::` have nowhere to go.
+
+Its stdout is part of the job log, inside a collapsible group, and is scanned for workflow commands. `::add-mask::` registers a value to be masked for the rest of the job, `::set-env::` and `::add-path::` apply to the steps that follow.
+
+`$GITHUB_ENV` and `$GITHUB_PATH` point at files that are read back after the hook exits, so the file-command form works too:
+
+```bash
+#!/bin/bash
+echo "REGISTRY_TOKEN=$(fetch-token)" >> "$GITHUB_ENV"
+echo "/opt/tooling/bin" >> "$GITHUB_PATH"
+```
+
+Both files are the hook's own, separate from the per-step ones, so nothing a hook writes is truncated by the first step.
+
+## Recommendations
+
+- Keep hooks **fast** and return the right exit code: they are on the critical path of every job, and nothing bounds them.
+- Use **idempotent** operations, and expect `job_completed` to run after success, failure, and cancellation alike.
+- Mask anything secret the hook prints or exports with `::add-mask::`.
