refactor(skills): migrate commands to skills directory structure

Move all 27 command .md files from commands/ to skills/*/SKILL.md
format. Claude Code 2.1.3+ merged commands and skills - both create
slash commands and work identically. Skills add optional features
like supporting files and automatic context loading.

- commands/ce/*.md -> skills/ce-*/SKILL.md
- commands/workflows/*.md -> skills/workflows-*/SKILL.md
- commands/*.md -> skills/*/SKILL.md
- Update plugin.json and marketplace.json descriptions
- Update CLAUDE.md directory structure docs
- Update deploy-docs and generate_command references

Fixes #116

+
+# Reproduce Bug Command
+
+Look at github issue #$ARGUMENTS and read the issue description and comments.
+
+## Phase 1: Log Investigation
+
+Run the following agents in parallel to investigate the bug:
+
+1. Task rails-console-explorer(issue_description)
+2. Task appsignal-log-investigator(issue_description)
+
+Think about the places it could go wrong looking at the codebase. Look for logging output we can look for.
+
+Run the agents again to find any logs that could help us reproduce the bug.
+
+Keep running these agents until you have a good idea of what is going on.
+
+## Phase 2: Visual Reproduction with Playwright
+
+If the bug is UI-related or involves user flows, use Playwright to visually reproduce it:
+
+### Step 1: Verify Server is Running
+
+```
+mcp__plugin_compound-engineering_pw__browser_navigate({ url: "http://localhost:3000" })
+mcp__plugin_compound-engineering_pw__browser_snapshot({})
+```
+
+If server not running, inform user to start `bin/dev`.
+
+### Step 2: Navigate to Affected Area
+
+Based on the issue description, navigate to the relevant page:
+
+```
+mcp__plugin_compound-engineering_pw__browser_navigate({ url: "http://localhost:3000/[affected_route]" })
+mcp__plugin_compound-engineering_pw__browser_snapshot({})
+```
+
+### Step 3: Capture Screenshots
+
+Take screenshots at each step of reproducing the bug:
+
+```
+mcp__plugin_compound-engineering_pw__browser_take_screenshot({ filename: "bug-[issue]-step-1.png" })
+```
+
+### Step 4: Follow User Flow
+
+Reproduce the exact steps from the issue:
+
+1. **Read the issue's reproduction steps**
+2. **Execute each step using Playwright:**
+   - `browser_click` for clicking elements
+   - `browser_type` for filling forms
+   - `browser_snapshot` to see the current state
+   - `browser_take_screenshot` to capture evidence
+
+3. **Check for console errors:**
+   ```
+   mcp__plugin_compound-engineering_pw__browser_console_messages({ level: "error" })
+   ```
+
+### Step 5: Capture Bug State
+
+When you reproduce the bug:
+
+1. Take a screenshot of the bug state
+2. Capture console errors
+3. Document the exact steps that triggered it
+
+```
+mcp__plugin_compound-engineering_pw__browser_take_screenshot({ filename: "bug-[issue]-reproduced.png" })
+```
+
+## Phase 3: Document Findings
+
+**Reference Collection:**
+
+- [ ] Document all research findings with specific file paths (e.g., `app/services/example_service.rb:42`)
+- [ ] Include screenshots showing the bug reproduction
+- [ ] List console errors if any
+- [ ] Document the exact reproduction steps
+
+## Phase 4: Report Back
+
+Add a comment to the issue with:
+
+1. **Findings** - What you discovered about the cause
+2. **Reproduction Steps** - Exact steps to reproduce (verified)
+3. **Screenshots** - Visual evidence of the bug (upload captured screenshots)
+4. **Relevant Code** - File paths and line numbers
+5. **Suggested Fix** - If you have one
