Detailed Description

A bounded lookaround sub-program, referenced by assert_lookaround's arg16.

The sub-pattern's bytecode lives as a region inside the main code buffer (appended after the main program), so it survives copy/move of dynamic_program with no stored pointers — the views are rebuilt on demand from these offsets. l_max bounds the bytes the sub can consume (unbounded sub-patterns are rejected at compile time): the source of the strict linear-time guarantee.
