fix(discord-bridge): zgomot in bot.log si doua tipuri de stream necunoscute

Trei lucruri observate in logurile de productie dupa restartul precedent.

1. Ecoul propriilor mesaje umplea bot.log cu WARNING. Propriile mesaje au si
   ele `author.bot == True`, iar verificarea generica de bot venea INAINTEA
   celei pe `self_id` — deci raspunsurile botului se jurnalizau ca "bot
   strain", la fiecare mesaj. Verificarea pe `self_id` trece prima (motivul e
   acum precis), iar refuzurile de rutina — propriile mesaje si ceilalti boti —
   merg la DEBUG. Guild / canal / utilizator strain si webhook raman WARNING:
   alea chiar sunt semnal de securitate si erau inecate in zgomot.

2. `tool_progress` (heartbeat la 30s cat timp o unealta ruleaza) devine
   eveniment `ToolProgress`. Mesajul live arata acum "⏳ ruleaza de 2m30s" sub
   unealta curenta — singurul semn ca un tur lung lucreaza si nu a inghetat.

3. `rate_limit_event` devine eveniment `RateLimit` si apare in `/status` la
   randul `utilizare`. Cum nu exista plafon de cost (abonament, nu API),
   fereastra de utilizare e singura limita reala; se avertizeaza in log o data
   per schimbare de stare, nu la fiecare eveniment.
