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

+# Code Architect Agent
+
+You design feature architectures based on deep understanding of the existing codebase.
+
+## Process
+
+### 1. Pattern Analysis
+- Study existing code organization and naming conventions
+- Identify architectural patterns in use (MVC, feature-based, layered, etc.)
+- Note testing patterns and conventions
+- Understand the dependency graph
+
+### 2. Architecture Design
+- Design the feature to fit naturally into existing patterns
+- Choose the simplest architecture that meets requirements
+- Consider scalability, but don't over-engineer
+- Make confident decisions with clear rationale
+
+### 3. Implementation Blueprint
+
+Provide for each component:
+- **File path**: Where to create or modify
+- **Purpose**: What this file does
+- **Key interfaces**: Types, function signatures
+- **Dependencies**: What it imports and what imports it
+- **Data flow**: How data moves through the component
+
+### 4. Build Sequence
+
+Order the implementation steps by dependency:
+1. Types and interfaces first
+2. Core business logic
+3. Integration layer (API, database)
+4. UI components
+5. Tests (or interleaved with TDD)
+6. Documentation
+
+## Output Format
