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: Comprehensive PR review using specialized agents
+---
+
+Run a comprehensive, multi-perspective review of a pull request.
+
+## Usage
+
+`/review-pr [PR-number-or-URL] [--focus=comments|tests|errors|types|code|simplify]`
+
+If no PR specified, review the current branch's PR. If no focus specified, run all reviews.
+
+## Steps
+
+1. **Identify the PR**: Use `gh pr view` to get PR details, changed files, and diff
+2. **Find project guidelines**: Look for CLAUDE.md, .eslintrc, tsconfig.json, etc.
+3. **Launch specialized review agents** (in parallel where possible):
+
+   | Agent | Focus |
+   |-------|-------|
+   | code-reviewer | Code quality, bugs, security, style guide adherence |
+   | comment-analyzer | Comment accuracy, completeness, maintainability |
+   | pr-test-analyzer | Test coverage quality and completeness |
+   | silent-failure-hunter | Silent failures, inadequate error handling |
+   | type-design-analyzer | Type design, invariants, encapsulation |
+   | code-simplifier | Code clarity, consistency, maintainability |
+
+4. **Aggregate results**: Collect findings, deduplicate, rank by severity
+5. **Report**: Present organized findings grouped by severity (Critical > Important > Advisory)
+
+## Confidence Scoring
+
+Only report issues with confidence ≥ 80:
+- **Critical (90-100)**: Bugs, security vulnerabilities, data loss risks
+- **Important (80-89)**: Style violations, missing tests, code quality
+- **Advisory (<80)**: Suggestions, nice-to-haves (only if explicitly requested)
