docs: fix binary paths and tarball names across all documentation

Updated files:
- README.md: Fix tarball filename mt5-quant -> mcp-mt5-quant
- QUICKSTART.md: Fix tarball names and all binary paths
- WINDSURF.md: Fix tarball names, binary paths, and install script paths
- CURSOR.md: Fix tarball names and all binary path references
- VSCODE.md: Fix tarball names and all binary path references

All paths now correctly point to:
- Prebuilt: /path/to/mt5-quant/mcp-server/bin/mt5-quant
- Dev build: /path/to/mt5-quant/target/release/mt5-quant
