Multiple templates missing Non-Goals and Quality Checklist sections

[Alan-Jowett]

Summary

11 templates are missing one or both of the Non-Goals and Quality Checklist sections that CONTRIBUTING.md and bootstrap.md require.

Missing Quality Checklist

CONTRIBUTING.md quality checklist states: "Templates have a quality checklist section." The following 5 templates lack this section:

Template	Has Quality Checklist?
investigate-bug	No
investigate-security	No
review-code	No
plan-implementation	No
plan-refactoring	No

All other templates (13/18) have quality checklists.

Missing Non-Goals

bootstrap.md guidelines state: "Include non-goals in every assembled prompt." The following 6 templates lack a Non-Goals section:

Template	Has Non-Goals?
author-requirements-doc	No
author-design-doc	No
author-validation-plan	No
plan-implementation	No
plan-refactoring	No
author-release	No

All other templates (12/18) have Non-Goals sections.

Overlap

plan-implementation and plan-refactoring are missing both sections.

Suggested approach

Add template-appropriate Non-Goals and Quality Checklist sections to each affected template. These should be specific to each task, not generic boilerplate.
