Add credential preflight, categorized errors and operations guides

Sync workflow: every failure is now reported as `ERROR: [category] message`
with the categories configuration, credentials (HTTP 401), permissions
(HTTP 403) and api (other HTTP errors, unreachable service); HTTP 404 is a
configuration error. Before changing anything the workflow checks that the
GitHub token can administer the mirror repository and stops with a
permissions error otherwise. No secret value is printed.

Guides: onboarding (with runner labels, prerequisites and offline runner
symptoms), credentials (minimum permissions, preflight, rotation) and
troubleshooting (every message mapped to a category and a fix). README
capability table updated. MIL-002 records the verification of scoped
workflow support: Gitea 1.27.3 runs the workflow in this repository;
delivery to other repositories is not yet verified.

| 1 | Write brief use cases for the P1 candidates | Turn the DevOps use cases in the Project Plan appendix into use case documents under `docs/uc-NNN/`, after a use case diagram and user stories exist. | No | |
| 2 | Verify scoped workflow support on the instance | The Business Case lists this as an unverified assumption. Check the Gitea version and how a scoped workflow reaches a repository, then record the result. | No | |

Check the Gitea version and how a scoped workflow reaches a repository, then record the result. Result: Gitea 1.27.3 runs the scoped sync workflow in this repository (run 16); delivery to other repositories is not yet verified and is recorded in `guides/onboarding.md`. | No | |
| 3 | Write the repository onboarding steps | Describe how to consume the workflow (scoped or copied), which secrets to set and how to test the first run. | No | |
| 4 | Document least-privilege tokens | Determine the minimum Gitea token scope and GitHub fine-grained token permission that the sync needs, and document them. | No | |
| 5 | Add a credential preflight step | Before the sync, check that both tokens authenticate and have the needed access, and report the result without printing any secret. | No | |
