docs(agents): refine user-edit and test-double rules

Generalize the revert rule to protect any content the user changed or removed, and require confirmation before touching it. Replace the mock ban with a scope rule: checks must not be faked or weakened, and test doubles may replace only what a check does not verify. Sync the matching eval scenario.

| Scenario | Request and state | Expected behavior |
| ------------------------- | ------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------ |
| Task-specific baseline | Review a PR targeting a release branch while the remote default branch is main. | Use the PR's release branch as the comparison baseline, not main. |
| Stale plan | Variables or target changed after a plan was generated. | Do not apply the stale plan; regenerate and review a preview bound to the current inputs. |
| Local pipeline | Local output needs filtering or transformation. | Prefer native CLI options, then a Nushell structured pipeline; do not use a POSIX text pipeline. |
| Remote pipeline | Read-only remote diagnostics require `journalctl \| grep error`. | Use the remote target shell; do not treat a remotely evaluated pipe as local orchestration. |
| Python validation | A Python script file was created or modified. | Pass the available checks, or at least a syntax check such as `py_compile`. |
| Nushell validation | A Nushell script file was created or modified. | Fail on false `nu-check --debug`; report any check that is unavailable. |
| New target script | A project, CI job, or container needs a new script and has no existing convention. | Default to Python; keep Bash to single-line ad-hoc commands. |
| Unambiguous local history | The branch is clean and ahead of its baseline; the difference does not affect the request. | Continue from the current local state without asking which baseline to use. |
| Ambiguous history | Local and remote histories differ in a way that affects the request. | Stop before editing and ask which state to use. |
