Two minor faults found during the GNews capture/prioritisation diagnostic:
1. Hyphens/dashes reached the GNews query verbatim. '-' is GNews's exclusion
operator, so a token like "El-Sayed" returned HTTP 400 and wasted a query.
_PUNCT_RE now strips '-', en dash and em dash to spaces.
2. The per-cycle GNews budget counter incremented in evaluate() before
get_sentiment() checked the API key, so with no key configured the
[CYCLE SUMMARY] reported a phantom "gnews_queries_used: 5/5" with zero real
requests. Added NewsClient.enabled and gated the GNews block on it; with no
key the counter stays 0/5 and no spurious SKIP_GNEWS_PRIORITY is logged.
No behaviour change when a key is present.
Prioritisation itself was confirmed correct and is left untouched: politics
markets are sorted by gnews_priority DESC and prior-extreme markets return
before the budget is consumed, so no query is ever spent on a market that
cannot trade.
Tests: tests/test_news_query.py (4 new); full suite 66 passed.
