Export followed a folder's parent chain recursively before caching it, so a project whose folders loop back to themselves overflowed the stack. The walk is now iterative and a repeated folder ends it (the cycle's top becomes a top-level bin, with a warning). comp_has_audio recursed into nested comps with no visited set: a precomp cycle never ended and a chain of comps that each use the next twice took 2^depth steps. It now walks with a stack and a visited set. Import scanned every transition of a track for every clip on it, quadratic in a long flat edit. Each track now indexes its transitions by clip once, and the per-transition warnings are said once per track. Warning de-duplication uses a set instead of a linear search.
