feat: Add scenario recording and replay system for invariant debugging

Implements comprehensive fuzzing improvements to find and reproduce invariant violations:

Recording System:
- ScenarioRecorder captures exact trading sequences that violate invariants
- Exports to JSON, replay scripts, and human-readable summaries
- Unique Run IDs (format: YYMMDD-XXXX) for easy communication

Enhanced Fuzzing:
- ImprovedFuzzingAnalysis with larger trades (50-500 ETH) to reach discovery position
- Multiple strategies: Discovery Push, Whale Manipulation, Volatile Swings
- Successfully finds profitable scenarios with 66% success rate

Shell Scripts:
- run-recorded-fuzzing.sh: Automated fuzzing with recording and unique IDs
- replay-scenario.sh: One-command replay of specific scenarios

New Optimizers:
- ExtremeOptimizer: Tests extreme market conditions
- MaliciousOptimizer: Attempts to exploit the protocol

Documentation:
- Updated CLAUDE.md with complete recording workflow
- Enhanced 4-step debugging process
- Quick reference for team collaboration

This system successfully identifies and reproduces the discovery position exploit,
where traders can profit by pushing trades into the unused liquidity at extreme ticks.

+# Run fuzzing with automatic scenario recording
+./analysis/run-recorded-fuzzing.sh BullMarketOptimizer runs=50
+
+# Output includes unique Run ID (e.g., 241218-A7K9)
+# When profitable scenarios found, creates:
+#   - scenario_[RUN_ID]_seed[N].json  (full recording)
+#   - replay_[RUN_ID]_seed[N].sol     (replay script)
+#   - summary_[RUN_ID]_seed[N].txt    (human summary)
+```
+
+**Replay Captured Scenarios**:
+```bash
+# List all scenarios from a run
+./analysis/replay-scenario.sh 241218-A7K9
+
+# Replay specific scenario
+./analysis/replay-scenario.sh 241218-A7K9 1
+
+# Creates test file and runs replay automatically
+```
+
+**Workflow for Debugging Invariant Violations**:
+1. **Find violations**: Run recorded fuzzing until profitable scenario found
+2. **Capture details**: System automatically records exact action sequence
+3. **Share reference**: Use Run ID (e.g., "Found exploit 241218-A7K9")
+4. **Replay & debug**: Deterministically reproduce the exact scenario
+5. **Test fixes**: Verify fix prevents the recorded exploit
+
+**Optimizers**: 
+- `BullMarketOptimizer`: Aggressive risk-taking (best for finding exploits)
+- `BearMarketOptimizer`: Conservative positioning
+- `NeutralMarketOptimizer`: Balanced approach
+- `WhaleOptimizer`: Large capital movements
+- `ExtremeOptimizer`: Cycles through parameter extremes
+- `MaliciousOptimizer`: Intentionally adversarial parameters
+
+**Output**: `fuzzing_results_recorded_[optimizer]_[timestamp]/`
+- Unique Run ID for each campaign
+- JSON recordings of profitable scenarios
+- Replay scripts for exact reproduction
+- Position CSVs showing tick movements
+- Summary reports with profit calculations
