Add conformance tests for SEP-1330 elicitation enums (#22)

* Add SEP-1330 conformance test for elicitation enum schemas

Adds server-side conformance test that validates servers properly request
elicitation with SEP-1330 enum schema improvements:
- Untitled single-select enum (type: string, enum: [...])
- Titled single-select enum (oneOf with const/title)
- Legacy titled enum (enumNames for backward compatibility)
- Untitled multi-select enum (type: array, items.enum)
- Titled multi-select enum (items.anyOf with const/title)

Test expects server to implement `test_elicitation_sep1330_enums` tool.

* Add reference server implementation for SEP-1330 conformance test

Adds test_elicitation_sep1330_enums tool to everything-server that
requests elicitation with all 5 enum schema variants. Also updates
SERVER_REQUIREMENTS.md with full specification.

* Fix prettier formatting

* only test active tests (#24)

* refactor maps to pull names from the test

* bring names back

* separate active from pending

* only test active
