refactor: break up search_memories() into focused helpers

Extract _build_memory_filter(), _fetch_memory_candidates(),
_row_to_entry(), and _score_and_rank() from the 82-line
search_memories() function for better readability and testability.

Fixes #554

+  The `epoch` field carries the symbolic notation.

 SUCCESS DEFINITION:
   A cycle is only "success" if BOTH conditions are met:
     1. The hermes process exited cleanly (exit code 0)
     2. Main is green (smoke test passes on main after merge)
-

   A cycle that merges a PR but leaves main red is a FAILURE.
