Address three parser hot spots in auditd ingest processing. - Replace one monolithic grok with conditional grok paths to avoid failing expensive patterns on unrelated events. - Remove unbounded quoted payload matching from the msg branch by using quote-bounded classes. - Replace the fallback key-value capture shape that relied on GREEDYDATA-style scanning with bounded pre-captures and safer fallback matching for non-kv records. On benchmark pipeline runs, processing_time dropped from 0.42s (source_doc_count=70, doc_count=1000) to 0.08s in this branch. The previous single grok hot spot at 75% total time and 315us/doc is no longer dominant after splitting and bounding captures. Also bump auditd package version to 3.22.2 and add a changelog bugfix entry for the backtracking fix.
