Module regret_tracker 

Compression Regret Tracker — learns from compression mistakes to improve future decisions per-file and per-content-type.

When the LLM re-reads a file that was served from dedup cache, or when the verifier triggers a safe-mode fallback, that’s a “regret event.” The tracker records these and adjusts compression aggressiveness per file.

NOTE: this in-memory tracker is not wired into the hook path (each hook invocation is a fresh process, so nothing here persists). The shipped regret signals live in the session store’s regret_log table — written by CliProxy (quick reruns) and CacheManager::expand_prefix (ref expands), surfaced by sqz stats.
