docs(claude/memory): capture PR-review comment-style feedback

Add two memories and correct one existing, from a review of PR comments
across multicluster and unified-helm over the past two months:

- code_comment_style: no Jira/ticket IDs in code comments by default,
  keep comments concise and about the non-obvious why, and use # (not
  Helm template) comments where they must reach the rendered manifest.
- copilot_review_false_positives: verify Copilot blocking claims against
  the spec and live config before acting; records two Terraform FPs.
- workflow_review_and_comments: drop the now-contradicted 'one-liner +
  WSP ticket reference' guidance, which reviewers repeatedly strip.
