fix: implement source distinction in agent responses

Add SOURCE DISTINCTION instructions to both lite and full system prompts, requiring Timmy to cite grounded sources (memory/retrieval) and hedge appropriately when inferring. Label memory context as "GROUNDED CONTEXT" so the model can distinguish retrieved facts from pattern-matching. Fixes #463 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

 Called after each cycle completes (success or failure).
 Appends a structured entry to .loop/retro/cycles.jsonl.
 EPOCH NOTATION (turnover system):
  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)
  D   ISO weekday (1=Mon … 7=Sun)
  NNN daily cycle counter, zero-padded, resets at midnight UTC
  Example: ⟳12.3:042 — Week 12, Wednesday, 42nd cycle of the day.
  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.
  The --main-green flag records the smoke test result.
