nx_http_chunked.nx

nx_http_chunked.nx -- LIB: HTTP/1.1 chunked transfer-encoding DECODER (RFC 7230 §4.1). THE concrete M2 unblock: HuggingFace's dynamic API responses (the repo /tree enumerate) are chunked with NO Content-Length, so our Content-Length reader blocks on them (this is exactly why nx_mirror_live_probe's tree fetch hung). This decodes a chunked body buffer -> the raw bytes, so enumerate can proceed. Pure parsing (no crypto, no TLS) -> imports nx_syscalls only (composes cleanly beside the TLS fetch stack, unlike nx_sha256). No 'break' (nx) -> flag-driven loops. Bounded by the input length (never reads past src[n]). license_tier: ORIGINAL
