feat(skills): bundle minimum skill set from claude-skills into factory/skills/

Copies 8 standalone skills (active-platform, caveman, project-discipline,
pulling-before-work, setup-tasks, setup-wiki, using-tasks, using-wiki) from
~/projects/claude-skills/skills/ and all 14 superpowers sub-skills from the
installed plugin cache into factory/skills/superpowers/.

Adds skills install step to bootstrap.ps1: copies all factory/skills/
directories to ~/.claude/skills/ so users get the skill set automatically
without manual plugin install for the baseline set.

+# Code Quality Reviewer Prompt Template
+
+Use this template when dispatching a code quality reviewer subagent.
+
+**Purpose:** Verify implementation is well-built (clean, tested, maintainable)
+
+**Only dispatch after spec compliance review passes.**
+
+```
+Task tool (general-purpose):
+  Use template at requesting-code-review/code-reviewer.md
+
+  DESCRIPTION: [task summary, from implementer's report]
+  PLAN_OR_REQUIREMENTS: Task N from [plan-file]
+  BASE_SHA: [commit before task]
+  HEAD_SHA: [current commit]
+```
+
+**In addition to standard code quality concerns, the reviewer should check:**
+- Does each file have one clear responsibility with a well-defined interface?
+- Are units decomposed so they can be understood and tested independently?
+- Is the implementation following the file structure from the plan?
+- Did this implementation create new files that are already large, or significantly grow existing files? (Don't flag pre-existing file sizes — focus on what this change contributed.)
+
+**Code reviewer returns:** Strengths, Issues (Critical/Important/Minor), Assessment
