Document baseline test failure handling and block work until resolved

[mcj-coder]

Summary

Add a documented rule for baseline verification failures: create or reference a blocking issue and pause work until baseline passes.

Acceptance Criteria

• AGENTS.md states baseline failures must be addressed immediately (commit 5afba31)
• AGENTS.md states current work is blocked until baseline passes (commit 5afba31)
• CLAUDE.md mirrors the same baseline failure rule (commit 5afba31)
• Guidance requires creating a blocking issue if none exists (commit 5afba31)

Notes

• Applies when using worktrees and baseline tests fail.
