V0.12.7

Release v0.12.7

New Feature – Literal Type Support in Tools

The @simple_tool decorator now understands Python’s Literal type hints.
Literal["a", "b"], Literal[1, 2, 3] (and homogeneous float / bool literals) are automatically converted to JSON Schema with an enum constraint, making it easy to define allowed values for LLM function calling.

Mixed‑type literals (e.g., Literal["a", 1]) raise a clear TypeError at registration time.

Documentation

• English and Chinese guides have been updated to cover the new Literal support and constraints.

Internal Improvements

• Added Ruff PERF rule and ignored RUF036 (preview) to maintain code quality.
• Several type annotations were refined (e.g., get_current_datetime_timestamp, get_tool_meta, get_tool_func, MCPProperty).
• Imports were re‑sorted (isort) and a few formatting inconsistencies fixed.
