docs: Complete Phase 2 & 3 - Replace all false product examples

🎯 Zero false claims - all examples now authentic or generic

**Problem Solved:**
- 28 false Twitter references eliminated
- All examples now use real product capabilities
- Zero fictional integrations remain

**Changes Summary:**

**README.md (3 replacements):**
- Adaptive example: Twitter → Perch MCP (D1 database introspection)
- Contextual example: Twitter bot → D1 query optimization
- Efficient example: Twitter integration → Database performance analysis

**PRINCIPLES.md (24 replacements):**

*Proactive Section:*
- Anticipatory suggestions: Twitter bot → Database optimization

*Adaptive Section:*
- Beginner/expert examples: Twitter/Chirp → Perch MCP (D1 analysis)
- Progressive disclosure: Twitter OAuth → D1 connection modes

*Contextual Section:*
- Conversation memory: Twitter bot → D1 query performance
- Context synthesis: Twitter preferences → Database optimization needs
- Executive Summary Panel: Twitter bot → D1 performance issues
- Transparent reasoning: Twitter + open source → D1 + optimization

*Efficient Section:*
- Lead with answer: Twitter integration → Database performance (Perch)
- Eliminate filler: Twitter connection → D1 analysis
- Appropriate depth: Chirp rate limiting → Perch index recommendations

*PACE in Practice:*
- Complete example: Twitter bot tutorial → Chirp MCP (Yahoo Fantasy Hockey)
- Real commands: `npx @modelcontextprotocol/create-server chirp`
- Authentic use case: "Check my roster for injured players"

**New File: REPLACEMENT_EXAMPLES.md**
- 18 comprehensive examples (7 generic, 5 Chirp, 3 Perch, 3 Wake)
- All demonstrate PACE principles
- All use real product capabilities
- Beginner/intermediate/expert coverage

**Verification:**
✅ Zero "Twitter" references in core docs
✅ All product claims verifiable
✅ Authentic Chirp examples (Yahoo Fantasy Hockey)
✅ Real Perch examples (D1 database introspection)
✅ Generic examples work across domains

**Quality Maintained:**
- All PACE principles still demonstrated
- Example quality improved (real > fictional)
- Credibility significantly enhanced
- Ready for academic archival

**Files Modified:**
- README.md (3 examples replaced)
- PRINCIPLES.md (24 examples replaced)
- New: REPLACEMENT_EXAMPLES.md (18 examples)

**Phase 2 & 3:** ✅ COMPLETE
**Next:** Phase 4 (Final verification) → Phase 5 (Wayback Machine archival)
