docs(tooling): correct two LuaDoc annotations from copilot review

- attach_endpoint: mark opts.default_port optional (`default_port?`); the
  python DAP caller omits it to mean "port required", which the previous
  `integer|nil` value type wrongly flagged as a missing field.
- resolve_runtime_tools: add the `reason` field to the probe return type —
  info() reads result.reason (the conform probe's per-buffer unresolved case),
  but the annotation omitted it.

Annotation-only; no runtime change.
