fix: version mismatch between __init__.py (0.0.17) and pyproject.toml (0.0.18)

[alfonsodg]

Problem

The package version is defined in two places with different values:

• minimax_mcp/__init__.py: __version__ = "0.0.17"
• pyproject.toml: version = "0.0.18"

Exact location

• minimax_mcp/__init__.py:3 — __version__ = "0.0.17"
• pyproject.toml:3 — version = "0.0.18"

Impact

• importlib.metadata.version("minimax-mcp") returns 0.0.18 (from pyproject.toml)
• minimax_mcp.__version__ returns 0.0.17 (from init.py)
• Confusing for debugging and version tracking

Proposed solution

Use a single source of truth for versioning. Two options:

Option A (recommended): Use importlib.metadata in __init__.py:

from importlib.metadata import version
__version__ = version("minimax-mcp")

Option B: Sync manually — update __init__.py to 0.0.18 and add a CI check that both match.

Acceptance criteria

• minimax_mcp.__version__ matches the version in pyproject.toml
• Only one source of truth for the version number
