…adding LRU eviction (LOG-9336) Adds a three-layer defense against file descriptor exhaustion: 1. Auto-raise RLIMIT_NOFILE soft limit to hard limit at startup, with macOS kern.maxfilesperproc fallback for RLIM_INFINITY hard limits. 2. New `max_open_files` config for the file source with LRU eviction — when the limit is reached, the least recently read file is closed (checkpoint preserved, no data loss). 3. Auto-derive a sensible default (80% of OS soft limit) so the feature works out of the box without manual configuration. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
