feat(podcasts): make podcasts always available + smarter mention matching

Changes:
- Podcasts source is now always available when yt-dlp is installed (same as
  YouTube). Previously required explicit opt-in via INCLUDE_SOURCES or
  --search=podcasts.
- Smarter mention matching: extract key terms from multi-word topics and
  use max count across terms. "Kanye West Bully album" now matches
  episodes mentioning "Kanye" 85 times (previously 0 due to exact phrase).
- SKILL.md: add podcast channel resolution to Step 0.55, include
  --podcast-channels in execution command, update ACTIVE_SOURCES_LIST.

Tested: Kanye West query now finds 5 podcast hits including hidden
mentions in off-topic episodes (Lost Civilizations, Mike WiLL Made-It).

+   - Tech/AI/startups → `lexfridman,DwarkeshPatel,AllInPod,MyFirstMillionPod,LennysPodcast`

+   - Culture/celebs → `joerogan,CallHerDaddy,ClubShayShay`
+   - Knitting/crafts → `FruityKnitting,VeryPinkKnits,GroceryGirlsKnit`
+
+2. **Cross-domain podcasts** — What popular interview/deep-dive podcasts might cover this topic even if it's not their main focus?
+   - Business-adjacent topics → `AcquiredFM,InvestLikeTheBest` (company deep dives)
+   - Tech-adjacent topics → `lexfridman,AllInPod` (broad tech interviews)
+   - Culture-adjacent topics → `joerogan,OfficialFlagrant` (celebrity interviews)
+
+**Rationale:** The engine uses these channels for transcript-first discovery. Even if the topic isn't in an episode title, it may be discussed within the episode. Acquired's "The NFL" episode mentions Taylor Swift 18 times, ESPN 117 times — invisible to YouTube search but found by transcript scanning.
+
+**Handle accuracy:** Return your best guess at the exact @handle. If wrong, the engine falls back to a search-based lookup. Don't stress the exact spelling — `@AcquiredFM`, `@lexfridman`, `@joerogan` work; `@FLAGRANT` fails but falls back to find `@OfficialFlagrant`.
