v0.1.8

Fixed

• Renamed base exception class from RouterSmitError to RoutesmithError (typo fix).
• Removed unused import time from metrics.py and import os from state.py.
• Moved import math from inside function body to module level in planner.py.
• Fixed TOML fallback parser not parsing float values (e.g. 7.5 stayed as a string).

Changed

• hosts/__init__.py now exports all host adapters (Aider, ClaudeCode, Codex, Copilot, Cursor, GeminiCLI, Generic) instead of only GeminiCLI.
