Replace large stack allocations (1MB in commit_report_backtrace and 4MB in report functions) with dynamic memory allocation (malloc/free) to prevent stack overflow crashes, especially in thread contexts. Introduce commit_report_common helper to consolidate reporting logic, which also reduces code duplication by ~700 lines. Signed-off-by: Phineas Su <pohaosu@google.com>
