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

+## Content Types by Platform
+
+### X/Twitter Content Mix
+
+| Type | Frequency | Example |
+|------|-----------|---------|
+| Educational/tips | 3-4/week | "5 mistakes with [tool]", model selection, config tips |
+| News/commentary | 2-3/week | CVE breakdowns, industry news, product launches |
+| Milestones | 1-2/week | Star counts, test counts, download numbers |
+| Personal/journey | 2-3/week | Builder life, founder diary, lessons learned |
+| Ship logs | 2/week (weekends) | "sunday ship log: [list]" |
+| Engagement bait | 1-2/week | "what's one thing you want [product] to do better?" |
+
+### Engagement Bait Formats
+- "what's your [X]?" (config sharing, stack sharing)
+- "hot take: [contrarian opinion]" (disagreement drives engagement)
+- "[thing] vs [thing]. go." (tribalism)
+- "what am I missing?" (vulnerability + question)
+
+### Viral Mechanics
+- Large specific numbers: "1,184 malicious AI plugins"
+- Security scares: "your AI has access to your SSH keys"
+- Zero-X framing: "zero marketing budget. zero ads. just useful open source."
+- Before/after comparisons: default vs configured
+- Personal vulnerability: "ran the scan on my own config. grade B."
+- Contrarian takes: "stop using [expensive thing] for everything"
+
+### TikTok Script Structure
+```
+HOOK (0-3s): [visual/verbal pattern interrupt]
+PROBLEM (3-10s): [what's broken, what people don't know]
+SOLUTION (10-40s): [demo, walkthrough, the thing]
+CTA (40-60s): [what to do next]
+```
+
+### YouTube Script Structure
+- Hook (first 15s): Show the result, then explain how
+- Intro (15-30s): Who you are, what this covers, why it matters
+- Chapters (2-3 min each): One concept per chapter, new visual every 30 seconds max
+- Outro: Clear CTA (star repo, subscribe, try product)
+- Description: first 2 lines matter (above fold), include links, chapters
+
+## Content Recycling Flow
+
+```
+YouTube (highest effort)
+  -> Newsletter (long-form written adaptation)
+    -> LinkedIn (professional 3-takeaway version)
+      -> X/Twitter (atomic tweet units)
+        -> TikTok (15-60s visual snippet)
+```
+
+Adapt, don't duplicate. Each platform version should feel native.
+
+## Posting Schedule
+
+| Slot | Time | Content Type |
+|------|------|-------------|
+| Morning (7-8am) | - | Primary: educational, technical, news |
+| Midday (11:30am-12:30pm) | - | Engagement: question, hot take, QT |
+| Evening (5-6pm) | - | Secondary: ship log, personal, lighter |
+| Throughout day | - | 5-10 replies to relevant accounts |
