Handle EOL-Only Prose Diffs

[ptr727]

Summary

• Ignore carriage-return-only differences when scoping prose findings.
• Cover EOL renormalization and genuine content edits with a Git-backed regression test.
• Identify repo-config paths as hub-hosted in the workflow skill reference.

Addresses #869 and #870.

Verification

• ruff check and format check
• mypy
• 731 Python unit tests with 79% aggregate coverage
• build distribution, repository, prose, JSON, and spec gates

The executor's Docker daemon could not expose the worktree to the read-only container mounts, so the editorconfig-checker, ShellCheck, and PSScriptAnalyzer container gates were unavailable locally.

Pull request overview

Updates the prose-gate scoping logic so a CRLF↔LF renormalization commit doesn’t get treated as “every line changed,” and adds regression coverage plus documentation updates to reflect hub-hosted repo-config/ paths.

Changes:

• Add --ignore-cr-at-eol to the git diff used by prose_lint.changed_lines() so EOL-only diffs don’t expand the scope.
• Add a Git-backed unit test covering EOL-only renormalization vs genuine content edits.
• Update operational workflow skill references (and generated copies) to describe repo-config/ as hub-hosted; refresh the plugin source digest.

• The new test creates a temporary git repo and commits, but it doesn’t disable commit signing. If a developer has commit.gpgsign=true globally, git commit here can fail (missing key/pinentry), making the test non-hermetic. Other tests in this file explicitly set commit.gpgsign=false for this reason.

        subprocess.run(["git", "-C", str(root), "config", "core.autocrlf", "false"], check=True)
        subprocess.run(["git", "-C", str(root), "config", "user.name", "Test"], check=True)
        subprocess.run(
            ["git", "-C", str(root), "config", "user.email", "test@example.invalid"], check=True
        )

scripts/tests/test_prose_lint.py:1743: The temporary Git repository does not disable commit signing, so global commit.gpgsign=true can make the test non-hermetic.

Fixed in 87aa49c. The test now sets commit.gpgsign=false inside its temporary repository before committing.

Review round: #881 (review)
