cmd: add auth status command

[somanshreddy]

Description

Adds heygen auth status — verifies the stored API key is valid by calling GET /v3/user/me and outputting account info.

# Valid key
$ heygen auth status
{"data":{"email":"user@example.com","username":"demo",...}}

# Invalid key → exit 3
$ heygen auth status
{"error":{"code":"auth_error","message":"invalid API key"}}

# No key configured → exit 3
$ heygen auth status
{"error":{"code":"auth_error","message":"no API key found","hint":"Set HEYGEN_API_KEY env var or run: heygen auth login"}}

skipAuth restructured: Moved skipAuth annotation from the auth group to auth login specifically. auth status intentionally resolves auth — if no key is configured, it fails with the standard auth error (exit 3) before the API call. auth login continues to skip auth as before.

Reuses generated spec: Calls ctx.client.Execute(gen.UserMeGet, ...) — same endpoint as heygen user me get. If the API path or response shape changes, both commands update together.

Auth vs server errors: Distinguishable by exit code. Invalid key → exit 3 (auth_error). Server down → exit 1 (server_error/network_error). Retry transport handles transient failures before surfacing.

Stacked on PR #43 (SKILL.md).

Testing

3 tests: success (200 → exit 0, stdout has user email), invalid key (401 → exit 3, stderr has auth_error), no key (exit 3 with hint to set env var or run auth login).

Existing TestAuthLogin_SkipsAuth continues passing — skipAuth annotation moved to login, not removed.

All tests use httptest.Server — no real API calls.
