fix(ai): guard zero-int detection cooldown and duplicate pet friends (#2667)
Supersedes #2658 (rebased onto main; edits by maintainers were not enabled on the original branch). Credit to @MithrilHammer for both fixes and the regression tests; their three commits are kept as authored.

Addresses two items from #2627:

- The detect-hidden cooldown clamps its divisor to at least one. A creature whose effective intelligence reaches zero now uses the existing capped cooldown instead of throwing.
- Pet friends are unique. `AddPetFriend` ignores an existing friend, so one removal revokes the membership.

On top of that, `AddPetFriend` and `RemovePetFriend` now go through the generated `AddToFriends` / `RemoveFromFriends`, which mark the creature dirty. `Friends` goes back to null when the last friend is removed, and removing a non-friend no longer touches the list.

Duplicates already stored in saves are not migrated.

## Tests

`DetectHiddenTimerTests` (7 cases) drives the real AI timer and checks cooldown bounds and retry timing. `PetFriendMembershipTests` (3 cases) covers duplicate adds, removal, and re-adding without disturbing other friends. `UOContent.Tests`: 1158 passed, 2 skipped, 0 failed on Windows.
