tighten retry scope, RU-only lyrics text cache, fix theme pattern and dedupe log

with_retries caught bare Exception with a type whitelist, masking real bugs
as network errors under retry/backoff - narrowed back to NetworkError.

fetch_api_languages was writing full lyrics text for every language into
lyrics_text.json via its track_supplement side channel, breaking the
documented RU-only invariant and letting analyze feed foreign-language
lyrics through the Russian-only prompt - now gated on normalize_api_language.

dedupe_playlists logged the found duplicate count as "removed" even when
a mid-loop network/API error cut deletion short.

THEME_PATTERN's relaxed regex allowed 2-char themes, contradicting its own
test; current_themes was hoisted out of the analyze loop so later prompts
never saw themes found earlier in the same run. Both reverted to intended
behavior, docs updated to match.
