go-sdk/mcp/testdata/conformance/server/tools.txtar

Check behavior of a server with just tools.

Fixed bugs:
- "tools/list" can have missing params
- "_meta" should not be nil
- empty resource or prompts should not be returned as 'null'
- the server should not crash when params are passed to tools/call
- missing required input fields should be rejected (#449)
- output and input should be validated against their actual json, not Go
	representation
- When arguments are missing, the request should succeed if all properties are
	optional, and observe any default values.
