feat: youtube_subs + dashboard includ descrierea video ca index

- tools/youtube_subs.py: get_subtitles() returneaza acum (title, desc, transcript).
  Functii noi is_description_about_video() si extract_relevant_description()
  detecteaza daca descrierea contine capitole/timestamps (nu doar promotie autori)
  si curata trailing-urile promotionale inainte sa includa descrierea in output.
- dashboard/handlers/youtube.py: aceleasi functii adaugate; nota KB generata
  include acum un bloc "Descriere / Index" daca descrierea e relevanta pentru video.
- memory/kb/youtube: nota Jeremy Grantham (AI bubble, investitii, toxicitate)
  cu descrierea ca index de capitole.
