- http_server: replace lazy log mutex init with 3-state UNINIT/INITING/INITED CAS pattern; cbm_ui_log_init() called from main before thread creation, also still invoked lazily from cbm_ui_log_append() so early single-threaded logs are not dropped - watcher: protect projects hash table with cbm_mutex_t (watch/unwatch/touch/watch_count/free); poll_once snapshots project pointers under lock then iterates without it so git I/O and indexing don't block watch/unwatch - watcher: handle state_new() OOM in watch path - compat_thread: add cbm_thread_detach() for POSIX and Windows; both join() and detach() clear the handle on success for consistent lifecycle tracking - http_server: detach index job threads to prevent handle leaks
