[Hackathon] Add a "doctor" command to diagnose CLI setup

What does this improvement do?

Add testsprite doctor: a one-shot diagnostic that checks CLI version, Node.js runtime, active profile, API endpoint, credentials, live connectivity (GET /me), and whether the verify skill is installed. It prints an OK/WARN/FAIL report and exits non-zero when any check fails, so it works as a CI or agent preflight (testsprite doctor && testsprite test run ...). The API key is never printed.

Details / implementation notes

New command in src/commands/doctor.ts, reusing existing helpers (loadConfig, makeHttpClient, assertValidEndpointUrl, isVerifySkillInstalled) so the report matches what a real command resolves. 12 unit tests. Registered in src/index.ts; root --help snapshot updated. Full gate green. PR to follow once assigned.

Triage: accepted — a preflight doctor is standard kit; reuse the real resolution helpers so the report matches actual command behavior, and never print the key. To claim it, comment /assign (the literal slash command — the triage bot only reacts to that exact form).
