Summary

Fixes issue #22, where MCP tool results were exported as {}.

OpenCode supplies different result shapes:

• Native tools: { title, output, metadata, attachments }
• MCP tools: { content: [...] }

The hook now normalizes these shapes:

• Native tool behavior remains unchanged.
• MCP text content is flattened into the recorded output.
• MCP results without a title use the tool name.
• Missing results remain empty.
• Unexpected non-null shapes produce a warning and are recorded as empty output rather than guessed at.

For example, a standard MCP text part such as
{ type: "text", text: "Search result" } is recorded as
"Search result". Non-text parts are represented by markers such as
"[image]" or "[resource]", matching the content-part types handled by
OpenCode's MCP tool processing.

Verification

• pnpm install
• pnpm run format
• pnpm run build
• pnpm run test:integration
• 14 integration tests passed
