CLI: --key value format passes numeric params as strings, causing invalid_type errors

[Skrblik]

Description

When using mcporter CLI v0.7.3, the --key value argument format passes all parameter values as strings, while the key=value format preserves types. This causes MCP servers to reject calls with invalid_type errors for numeric parameters like limit, pageNumber, etc.

Steps to Reproduce

# BROKEN - passes limit as string
mcporter call xpoz.getTwitterPostsByKeywords --query "test" --limit 5
# Result: MCP error -32602: Expected number, received string for 'pageNumber'

# WORKS - preserves types
mcporter call xpoz.getTwitterPostsByKeywords query="test" limit=5
# Result: success

Expected Behavior

Both --key value and key=value formats should preserve parameter types.

Environment

• mcporter version: 0.7.3
• OS: Windows 10
• MCP Server: Xpoz (https://mcp.xpoz.ai/mcp)
