* fix: add MFS operation limit for --flush=false adds a global counter that tracks consecutive MFS operations performed with --flush=false and fails with clear error after limit is reached. this prevents unbounded memory growth while avoiding the data corruption risks of auto-flushing. - adds Internal.MFSNoFlushLimit config - operations fail with actionable error at limit - counter resets on successful flush or any --flush=true operation - operations with --flush=true reset and don't count this commit removes automatic flush from https://github.com/ipfs/kubo/pull/10971 and instead errors to encourage users of --flush=false to develop a habit of calling 'ipfs files flush' periodically. boxo will no longer auto-flush (https://github.com/ipfs/boxo/pull/1041) to avoid corruption issues, and kubo applies the limit to 'ipfs files' commands instead. closes #10842 * test: add tests for MFSNoFlushLimit tests verify the new Internal.MFSNoFlushLimit config option: - default limit of 256 operations - custom limit configuration - counter reset on flush=true - counter reset on explicit flush command - limit=0 disables the feature - multiple MFS command types count towards limit * docs: explain why MFS operations fail instead of auto-flushing addresses feedback from https://github.com/ipfs/kubo/pull/10985#pullrequestreview-3256250970 - clarify that automatic flushing at limit was considered but rejected - explain the data corruption risks of auto-flushing - guide users who want auto-flush to use --flush=true (default) - document benefits of explicit failure for batch operations
