fix: add unit tests for memory/embeddings.py

Tests cover _simple_hash_embedding, cosine_similarity, _keyword_overlap,
embed_text, and _get_embedding_model with proper mocking of the global
model state.

Fixes #431

-  Each cycle carries a symbolic epoch tag alongside the raw integer:

-      ⟳WW.D:NNN
-
-  ⟳   turnover glyph — marks epoch-aware cycles
-  WW  ISO week-of-year (01–53)

-  The raw `cycle` integer is preserved for backward compatibility.
-  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.
