docs: Major documentation reorganization + ENV variable reference

**Documentation Structure:**
- Created docs/ subdirectory organization (analysis/, architecture/, bugs/,
  cluster/, deployments/, roadmaps/, setup/, archived/)
- Moved 68 root markdown files to appropriate categories
- Root directory now clean (only README.md remains)
- Total: 83 markdown files now organized by purpose

**New Content:**
- Added comprehensive Environment Variable Reference to copilot-instructions.md
- 100+ ENV variables documented with types, defaults, purpose, notes
- Organized by category: Required (Drift/RPC/Pyth), Trading Config (quality/
  leverage/sizing), ATR System, Runner System, Risk Limits, Notifications, etc.
- Includes usage examples (correct vs wrong patterns)

**File Distribution:**
- docs/analysis/ - Performance analyses, blocked signals, profit projections
- docs/architecture/ - Adaptive leverage, ATR trailing, indicator tracking
- docs/bugs/ - CRITICAL_*.md, FIXES_*.md bug reports (7 files)
- docs/cluster/ - EPYC setup, distributed computing docs (3 files)
- docs/deployments/ - *_COMPLETE.md, DEPLOYMENT_*.md status (12 files)
- docs/roadmaps/ - All *ROADMAP*.md strategic planning files (7 files)
- docs/setup/ - TradingView guides, signal quality, n8n setup (8 files)
- docs/archived/2025_pre_nov/ - Obsolete verification checklist (1 file)

**Key Improvements:**
- ENV variable reference: Single source of truth for all configuration
- Common Pitfalls #68-71: Already complete, verified during audit
- Better findability: Category-based navigation vs 68 files in root
- Preserves history: All files git mv (rename), not copy/delete
- Zero broken functionality: Only documentation moved, no code changes

**Verification:**
- 83 markdown files now in docs/ subdirectories
- Root directory cleaned: 68 files → 0 files (except README.md)
- Git history preserved for all moved files
- Container running: trading-bot-v4 (no restart needed)

**Next Steps:**
- Create README.md files in each docs subdirectory
- Add navigation index
- Update main README.md with new structure
- Consolidate duplicate deployment docs
- Archive truly obsolete files (old SQL backups)

+# Trading Bot v4 - Critical Issues Found & Fixes
+
+## Issue Summary
+
+Three critical issues discovered:
+
+1. **5-minute chart triggered instead of 15-minute** - TradingView alert format issue
+2. **SL orders not cancelled after winning trade** - Race condition + order calculation bug
+3. **No runner position (20% should remain)** - TP2 size calculation bug
+
+---
+
+## Issue 1: Wrong Timeframe Triggered
+
+### Problem
+- Trade executed on 5-minute chart signal
+- n8n workflow has correct filter for "15" timeframe
+- Filter checks: `timeframe === "15"`
+
+### Root Cause
+- n8n extracts timeframe with regex: `/\.P\s+(\d+)/`
+- Looks for ".P 5" or ".P 15" in TradingView message
+- Defaults to '15' if no match found
+
+### Solution
+**Check your TradingView alert message format:**
+
+Your alert should include the timeframe like this:
+```
+SOL buy .P 15
+```
+
+The ".P 15" tells n8n it's a 15-minute chart. If you're sending:
+```
+SOL buy .P 5
+```
+
+Then n8n will reject it (correctly filtering out 5-minute signals).
+
+**Verify n8n is receiving correct format by checking n8n execution logs.**
+
+---
+
+## Issue 2: SL Orders Not Cancelled
+
+### Problem
+- After winning trade, 2 SL orders remain on Drift ($198.39 and $195.77)
+- Bot detected "position closed externally" but found "no orders to cancel"
+
+### Root Cause
+**Race Condition in `/api/trading/execute`:**
+
+Current order of operations:
+1. Open position ✅
+2. Add to Position Manager (starts monitoring immediately) ⚠️
+3. Place exit orders (TP1, TP2, SL) ⏰
+
+If TP hits very fast (< 2-3 seconds):
+- Position Manager detects "external closure" while orders are still being placed
+- Tries to cancel orders that don't exist yet
+- Orders finish placing AFTER position is gone → orphaned orders
+
+### Solution
+**Reorder operations: Place exit orders BEFORE starting monitoring**
+
+---
+
+## Issue 3: No Runner Position
+
+### Problem
+- Config: `TAKE_PROFIT_2_SIZE_PERCENT=80` (should leave 20% runner)
+- Expected: TP1 closes 75% → TP2 closes 80% of remaining → 5% runner remains
+- Actual: Position 100% closed, no runner
+
+### Root Cause
+**BUG in `/home/icke/traderv4/lib/drift/orders.ts` lines 232-233:**
+
+```typescript
+const tp1USD = (options.positionSizeUSD * options.tp1SizePercent) / 100
+const tp2USD = (options.positionSizeUSD * options.tp2SizePercent) / 100
+```
+
+Both TP1 and TP2 are calculated as **percentages of ORIGINAL position**, not remaining!
+
+**With your settings (TP1=75%, TP2=80%, position=$80):**
+- TP1: 75% × $80 = $60 ✅
+- TP2: 80% × $80 = $64 ❌ (should be 80% × $20 remaining = $16)
+- Total: $60 + $64 = $124 (exceeds position size!)
+
+Drift caps at 100%, so entire position closes.
+
+### Solution
+**Fix TP2 calculation to use remaining size after TP1**
+
+---
+
+## Recommended Fixes
+
+### Fix 1: TradingView Alert Format
+
+Update your TradingView alert to include ".P 15":
+```
+{{ticker}} {{strategy.order.action}} .P 15
+```
+
+### Fix 2 & 3: Code Changes
