fix(lens): bound result recovery and preserve partial results (#44692)

* fix(lens): restate response contract during model repair

* fix(lens): separate instructions and recover rejected results

* fix(lens): correct loop type annotations and checks

* fix(lens): preserve access to prior findings after compaction

* fix(lens): cap result retries and preserve partial completion
