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: Create a git commit
+---
+
+Create a single git commit from staged and unstaged changes with an appropriate message.
+
+## Steps
+
+1. Run `git status` (never use `-uall` flag) and `git diff` in parallel to see all changes
+2. Run `git log --oneline -5` to match commit message style
+3. Analyze changes and draft a concise commit message following conventional commits format: `<type>: <description>`
+   - Types: feat, fix, refactor, docs, test, chore, perf, ci
+   - Focus on "why" not "what"
+4. Stage relevant files (prefer specific files over `git add -A`)
+5. Create the commit using a HEREDOC for the message:
+   ```bash
+   git commit -m "$(cat <<'EOF'
+   type: description
+   EOF
+   )"
+   ```
+6. Run `git status` to verify success
+
+**Rules:**
+- Never skip hooks (--no-verify) or bypass signing
+- Never amend existing commits unless explicitly asked
+- Do not commit files that likely contain secrets (.env, credentials.json)
+- If pre-commit hook fails, fix the issue and create a NEW commit
