* fix(filer): propagate multi-filer metadata log read errors A genuine (non not-found) read error in one filer's log stream was logged and skipped, then the merged cursor advanced past the gap, silently dropping that file's events. Abort the whole replay so the subscriber re-reads from the unchanged position; chunk-not-found still skips. * perf(mount): read persisted metadata log chunks directly from volume servers Set LogFileReaderFn so the filer returns log file references and the mount reads the chunk data itself, instead of the filer reading, decoding, and streaming every persisted entry. Keeps a reconnect storm of many mounts from concentrating hundreds of concurrent log replays in filer memory. * perf(filer): pre-size chunk stream reader buffer to view size The chunk size is known up front, so grow the buffer once instead of letting bytes.Buffer double as the streamed pieces arrive (which transiently overshoots to ~2x per reader). * fix(filer): bound concurrent persisted-log replays Each server-side replay holds an open chunk reader per source filer plus a readahead buffer, so a reconnect storm of clients that predate the metadata-chunks offload multiplies into many GB. Gate replays with a semaphore; abort the acquire when the subscriber's stream is gone so cancelled clients do not pile up parked goroutines.
