H2 settings subconfig. RFC 7540 §6.5.2 settings + the new-in-1.7 per-process ‘max_total_streams` admission cap (RFC A7).

max_header_list_size max_total_streams].freeze
AUTO =

2.0 default for ‘max_total_streams`. The literal value `:auto` is a deferred sentinel: `Config#finalize!` resolves it to `max_concurrent_streams × workers × 4` once the worker count is known. Operators wanting the pre-2.0 unbounded behaviour write `:unbounded` (or `nil` after finalize); operators wanting a fixed cap write a positive integer.
