feat(copilot): add dynamic wait time calculation for node startup

Browse Source 
Optimize GNS3StartNodeTool with device-type-aware wait time calculation
   to significantly reduce startup time for fast devices (VPCS, IOU).

   Changes:
   - Add NODE_STARTUP_TIME configuration
     * VPCS: 15s base + 2s per additional node
     * IOU: 25s base + 3s per additional node
     * Other devices: 120s base + 10s per additional node (conservative)

   - Add calculate_startup_time() function
     * Detects device types via node.node_type
     * Uses fast startup time if all nodes are VPCS/IOU
     * Uses conservative time if any slow device present
     * Logs selected strategy and detected types

   - Optimize GNS3StartNodeTool._run() method
     * Retrieve node info (including node_type) before starting
     * Calculate wait time based on detected device types
     * Send start commands after info retrieval
     * Use calculated wait time for progress bar
     * Reuse collected node objects for status retrieval

   Performance improvements:
   - 1 VPCS node: 140s → 15s (89% faster)
   - 5 VPCS nodes: 180s → 23s (87% faster)
   - 1 IOU node: 140s → 25s (82% faster)
   - 5 IOU nodes: 180s → 37s (79% faster)
   - Mixed VPCS/IOU: 180s → 33s (82% faster)

   Documentation:
   - Update node-control-tools.md with dynamic wait time strategy
   - Add device type comparison table
   - Document performance improvements
   - Update changelog

   Code quality:
   - All comments in English
   - flake8 check passed
   - mypy check passed

| Device Type | Base Time | Per Additional Node | Example (5 nodes) |
|-------------|-----------|-------------------|-------------------|
| **VPCS** | 10s | +2s | 18s total |
| **IOU** | 20s | +3s | 32s total |
| **Mixed VPCS/IOU** | 20s | +2s | 28s total |
| **VPCS** | 15s | +2s | 23s total |
| **IOU** | 25s | +3s | 37s total |
| **Mixed VPCS/IOU** | 25s | +2s | 33s total |
| **QEMU/Dynamips/Docker/VMs** | 120s | +10s | 160s total |
| **Mixed (any slow device)** | 120s | +10s | 160s total |
**How It Works:**
1. Retrieves node information including `node_type`
2. Checks if all nodes are fast devices (VPCS/IOU only)
3. If all fast: Uses max(10s, 20s) base + 2s per extra node
3. If all fast: Uses max(15s, 25s) base + 2s per extra node
4. If any slow device present: Uses 120s base + 10s per extra node
5. Logs the detected device types and chosen strategy
**Performance Improvements:**
- ⚡ **1 VPCS node**: 140s → 10s (93% faster)
- ⚡ **5 VPCS nodes**: 180s → 18s (90% faster)
- ⚡ **1 IOU node**: 140s → 20s (86% faster)
- ⚡ **5 IOU nodes**: 180s → 32s (82% faster)
- ⚡ **Mixed VPCS/IOU**: 180s → 28s (84% faster)
- ⚡ **1 VPCS node**: 140s → 15s (89% faster)
- ⚡ **5 VPCS nodes**: 180s → 23s (87% faster)
- ⚡ **1 IOU node**: 140s → 25s (82% faster)
- ⚡ **5 IOU nodes**: 180s → 37s (79% faster)
- ⚡ **Mixed VPCS/IOU**: 180s → 33s (82% faster)
**Use Cases:**
- Automated lab deployment

_Changelog:_
- **2026-03-14 (Evening)**: Added dynamic wait time calculation
- `GNS3StartNodeTool` now calculates optimal wait times based on device types
- Fast devices (VPCS: 10s, IOU: 20s) start much faster than before
- Fast devices (VPCS: 15s, IOU: 25s) start much faster than before
- Conservative timing accounts for slower hardware environments
- Slow devices (QEMU, Dynamips, etc.) use conservative 120s base time
- Performance improvements: 82-93% faster for VPCS/IOU labs
- Performance improvements: 79-89% faster for VPCS/IOU labs
- Automatic device type detection via `node.node_type`
- Logs selected strategy and detected device types
