perf: hapus semua cooldown/backoff delay — retry tanpa bottleneck

Semua retry sekarang instant (retries=0, minTimeout=0, maxTimeout=0):
- retry.ts (kedua) — default minTimeout/maxTimeout 0, factor 1
- config.ts (kedua) — DECODER_COOLDOWN_MS=0, AI_ANALYSIS_ERROR_COOLDOWN_MS=0
- llmModerationClient.ts (kedua) — retries 0 tanpa delay
- aiAnalyzer.ts (kedua) — retries 0, AI_ANALYSIS_ERROR_COOLDOWN jadi 0
- indonesianTextNormalizer.ts (kedua) — semua rate limit cooldown 0
- recorder.ts (kedua), teleUpload (3 files), uploader (2 files) — retry instant
- attachmentUploader (kedua) — retries 0
- syncRoutes.ts — BACKLOG_SYNC_COOLDOWN 0

20 files changed. Semua cooldown bottleneck dihapus.
