fix(ai-moderator): stop false cache-miss alarms when spam-log.json is absent

[Copilot]

The AI Moderator was triggering "Cache Configuration Problem" warnings on every run after cache expiry. The system-level cache_memory_prompt.md instructs agents to call missing_data(reason: cache_memory_miss) when expected cache data is absent, but a missing spam-log.json is entirely normal — the cache has retention-days: 1 and the file won't exist on first run or after daily expiry.

Changes

• ai-moderator.md: Sharpens the spam-log reading instruction to explicitly say the file may be absent due to cache expiry (not just "first run") and to proceed with an empty array without calling missing_data.

-At the start of your analysis, read the spam log file at
- `/tmp/gh-aw/cache-memory/spam-log.json` (it may not exist on the first run).
+At the start of your analysis, try to read the spam log file at
+ `/tmp/gh-aw/cache-memory/spam-log.json`. This file may not exist (it is absent
+ on the first run or whenever the 24-hour cache has expired) — if it is missing,
+ proceed with an empty array and **do not** call `missing_data`.

The lock file was recompiled after the change.

Changes:

• Clarify in ai-moderator.md that spam-log.json may be absent after cache expiry and should be treated as an empty log without calling missing_data.
