Task Objective:
Formulate the exact drop-in code fixes for `server/world/level_progression_service.py`:
1. **Level 100 Cumulative EXP Clamp**:
   In `award_monster_exp()`, when a player reaches Level 100, ensure `cumulative_exp` is strictly clamped:
   `cumulative_exp = min(self.get_canonical_benchmark(100).cumulative_exp, cumulative_exp)`
   And `exp_to_next_level = 0`.
   Verify that zero overflow past `24,285,477,315` is guaranteed.
2. **Level 100 Death Listener & Counter**:
   In `apply_death_penalty()`, remove the early return on `player.level >= 100`.
   Instead, for level 100, `penalty_ratio = 0.0` and `exp_lost = 0`, but:
   `deaths_count = player.deaths_count + 1`
   Update player state, and notify `_death_listeners` with the `DeathPenaltyResult`.
3. **EXP Non-Negative Sanitization**:
   In `award_monster_exp()`, sanitize `base_exp`: if `base_exp < 0` or calculated `raw_exp < 0`, clamp to `0`.
4. Keep file size strictly <= 350 lines (soft cap), <= 500 lines (hard cap).

Deliverables:
- Write report to `c:\Projects\FreeExile\.agents\teamwork\explorer_m2_progression_1_gen2\report.md`
- Write handoff to `c:\Projects\FreeExile\.agents\teamwork\explorer_m2_progression_1_gen2\handoff.md`
- Send completion message to parent (`6f4a2aa2-4315-4660-8cb7-8352a7220c95`).
