Add Unending Breath to Warlock NonCombat Strat (#2074)

# Pull Request

Adds actions and triggers for Warlock class to cast Unending Breath when
swimming, following the existing implementation for Shaman Water
Breathing.

---

## Feature Evaluation

Add triggers for Warlock noncombat strategy for Unending Breath on self
and party.
Triggers should only be active while swimming.
Minimal runtime cost on Warlock bots trigger processing.

---

## How to Test the Changes

- Bring a Warlock bot into water
- It should cast Unending Breath on itself and anyone in the party

## Complexity & Impact

- Does this change add new decision branches?
    - [ ] No
    - [x] Yes (**explain below**)
It adds triggers to Warlock to decide when to cast Unending Breath on
self or party members.

- Does this change increase per-bot or per-tick processing?
    - [ ] No
    - [x] Yes (**describe and justify impact**)
Minimal additional processing for Warlock triggers, same as already
existing triggers for Shaman.

- Could this logic scale poorly under load?
    - [x] No
    - [ ] Yes (**explain why**)

---

## Defaults & Configuration

- Does this change modify default bot behavior?
    - [x] No
    - [ ] Yes (**explain why**)

If this introduces more advanced or AI-heavy logic:

- [ ] Lightweight mode remains the default
- [ ] More complex behavior is optional and thereby configurable

---

## AI Assistance

- Was AI assistance (e.g. ChatGPT or similar tools) used while working
on this change?
    - [ ] No
    - [x] Yes (**explain below**)

Claude was used to explore the codebase to find similar implementations
that already existed.

---

## Final Checklist

- [x] Stability is not compromised
- [x] Performance impact is understood, tested, and acceptable
- [x] Added logic complexity is justified and explained
- [x] Documentation updated if needed

---

## Notes for Reviewers

Anything that significantly improves realism at the cost of stability or
performance should be carefully discussed
before merging.
