v1.0.0-beta.8

Changed

• Stall timeout raised from 60s to 3 minutes — Claude sonnet analyzing a real diff can legitimately take 1–2+ minutes before producing its first output token (especially with --output-format json which may buffer until the full response is ready). The 60s threshold was killing the process mid-analysis. 3 minutes gives normal runs enough headroom while still catching genuinely stuck processes.
• Idle heartbeat threshold raised from 15s to 30s — Reduces log noise during the first 30s of normal startup before the heartbeat countdown begins.
