test(label,milestone): cover tool registration and handler paths

Add operation/label/label_test.go verifying the label_read/label_write
tools register under the "label" scope with the expected method enums
and read/write classification, plus httptest coverage for
list_repo_labels and create_repo_label. Extend
operation/milestone/milestone_test.go with the equivalent registration
assertions and an httptest-backed list milestones test.

-# Docker image naming mismatch (issue #181)
-
-## Current state
-
-The project repository is `gitea.com/gitea/gitea-mcp`, but the Docker image is
-published as `docker.gitea.com/gitea-mcp-server`. This mismatch was raised in
-[issue #181](https://gitea.com/gitea/gitea-mcp/issues/181).
-
-## Maintainers' direction
-
-Per the issue discussion, the maintainers' preferred long-term name is
-`gitea/mcp-server`, matching the naming scheme used by `gitea/act_runner`
-(published as a `runner`-style short name) and by comparable projects such as
-`github/github-mcp-server`. The name `mcp-server` was preferred over
-`gitea-mcp-server` because the repository is primarily run as a local client
-process, not a traditional long-running server.
-
-## Decision
-
-No rename has happened yet; the discussion was explicitly left open in the
-issue. The current image name, `docker.gitea.com/gitea-mcp-server`, remains in
-use so that existing user configurations and documentation keep working.
-`org.opencontainers.image.title` and `org.opencontainers.image.description`
-labels were added to the `Dockerfile` to make the image self-describing
-regardless of the tag it is published under.
-
-If the image is renamed in the future, update the `docker.gitea.com/gitea-mcp-server`
-references across `README.md`, `README.zh-cn.md` and `README.zh-tw.md` together
-with this document.
