v1.0.1 — MCP stdio transport fix

Fixes #3 by reserving MCP stdio stdout exclusively for JSON-RPC messages.

Highlights:

• Removes full request and response diagnostics from the tool handler.
• Prevents invalid character 'r' connection failures in stdio clients.
• Keeps upstream API failures inside valid MCP tool results.
• Adds black-box success and failure tests against the packaged CLI.
• Avoids copying user prompts into stderr diagnostics.

Published:

• npm: enhance-prompt-server@1.0.1
• npm latest: 1.0.1
• SHA-1: 9e8e69aafa431fadd7afc78c45198cbddc88e3b5

Verification:

• npm test: 2/2 passing.
• Installed the local release tarball in a clean temporary consumer: 2/2 protocol tests passing.
• Installed enhance-prompt-server@1.0.1 from the public npm registry in a second clean consumer: 2/2 protocol tests passing.
• The public npm artifact shasum matches the verified GitHub release artifact.
