feat: consolidate all Anthropic plugins into ECC v2.0.0

Ports functionality from 10+ separate plugins into ECC so users only
need one plugin installed. Consolidates: pr-review-toolkit, feature-dev,
commit-commands, hookify, code-simplifier, security-guidance,
frontend-design, explanatory-output-style, and personal skills.

New agents (8): code-architect, code-explorer, code-simplifier,
comment-analyzer, conversation-analyzer, pr-test-analyzer,
silent-failure-hunter, type-design-analyzer

New commands (9): commit, commit-push-pr, clean-gone, review-pr,
feature-dev, hookify, hookify-list, hookify-configure, hookify-help

New skills (8): frontend-design, hookify-rules, github-ops,
knowledge-ops, lead-intelligence, oura-health, pmx-guidelines, remotion

Enhanced skills (8): article-writing, content-engine, market-research,
investor-materials, investor-outreach, x-api, security-scan,
autonomous-loops — merged with personal skill content

New hook: security-reminder.py (pattern-based OWASP vulnerability
warnings on file edits)

Totals: 36 agents, 69 commands, 128 skills, 29 hook scripts

+description: Commit, push, and open a PR
+---
+
+Commit all changes, push to remote, and create a pull request in one workflow.
+
+## Steps
+
+1. Run in parallel: `git status`, `git diff`, `git log --oneline -5`, check current branch tracking
+2. Stage and commit changes following conventional commit format
+3. Create a new branch if on main/master: `git checkout -b <descriptive-branch-name>`
+4. Push to remote with `-u` flag: `git push -u origin <branch>`
+5. Create PR using gh CLI:
+   ```bash
+   gh pr create --title "short title" --body "$(cat <<'EOF'
+   ## Summary
+   <1-3 bullet points>
+
+   ## Test plan
+   - [ ] Testing checklist items
+   EOF
+   )"
+   ```
+6. Return the PR URL
+
+**Rules:**
+- Keep PR title under 70 characters
+- Analyze ALL commits in the branch (not just the latest)
+- Never force push
+- Never skip hooks
