On macOS, the default file descriptor soft limit is 256. When watching many individual paths via FSEvents, the process can run out of file descriptors, causing
spawn EBADFerrors when spawning child processes.This PR adds a
max_fsevent_pathsoption (default 128) toConsolidatingPathTrie. When the number of watched paths exceeds this limit, the trie automatically consolidates bottom-up — replacing the deepest individual paths with their parent directories — until the count is under the limit. Distinct subtrees are never merged (e.g./a/...and/b/...won't consolidate to/).Event routing is unaffected and the callback already filters against the original watch set.
