/**
 * Decodes an unsigned LEB128 (little-endian base-128) varint at
 * `view[offset]`. Each byte contributes 7 bits of payload; the high bit is
 * a continuation flag.
 *
 * Returns the decoded `value` and the byte position `nextOffset` immediately
 * after the varint. Throws if the varint:
 *   - reads past the end of `view` (truncated),
 *   - exceeds 2**32-1 (overflow).
 *
 * Uses arithmetic (not bitwise) accumulation so values up to 2**32-1
 * round-trip correctly — JS bitwise operators coerce to signed int32 and
 * would turn 0xffffffff into -1.
