Add RSS Feeds adapter (6th source) — commercial AI news from 10 feeds

Bug fix: date parsing was ISO-only (RFC 2822 feeds filtered out).
Added email.utils.parsedate_to_datetime() fallback for RSS dates.

10 feeds: TechCrunch AI, VentureBeat AI, The Verge AI, AI News,
The Decoder, MIT Tech Review AI, OpenAI Blog, Anthropic, Google AI, Meta AI.

3 dead feeds (Anthropic/Google/Meta 404), 7 working.
Score: authority (primary blogs 1.5x, industry 1.3x) × recency decay (48h half-life)
Age cutoff: 14 days. Score type: estimated.

Wired into pipeline.py ENABLED_SOURCES. Added RSS URL verification.
3/3 spot-checks passed (all URLs reachable, HTTP 200).
