Jira: https://jira.mongodb.org/browse/EAI-2397

Why this change

• Every report case opens with the same message. Real users word the request in other ways, and some are terse or ask for more than the report covers.

Changes

• Adds query-insights-realistic-user-queries: seven cases on ported seeds, each with its own user message.
• The messages cover a visitor lookup, an admissions report, a task list, an expense API, distinct products, a terse request and an exact command.
• Registers the dataset in src/cli.ts.

Notes

• The seeds and expectations come from the ported cases. Only the user message is new.
• Each case copies the expected suggested indexes and reference of the case whose seed it reads. The same checks apply to a new wording.
• The messages are hand-written, not taken from real users. The one-off generator is not committed.
• Tests: the porting and query-insights suites pass at this commit.
