docs(issues): #8/#9/#11 filed; #10 wired (KillerNotification)

Files four new issues created by the 2026-04-25 PDB-discovery sprint:
  #8  (DONE 2026-04-25) — pdb-extract tool, shipped 69d884a
  #9  (OPEN)            — function-map address-correction sweep
                          (Phase E will close)
  #10 (DONE 2026-04-25) — wire KillerNotification (0x01AD); orphan
                          parser at GameEvents.ParseKillerNotification
                          existed but was never registered. This commit
                          adds CombatState.OnKillerNotification +
                          KillLanded event, registers the dispatcher
                          handler, and adds a regression test.
  #11 (OPEN)            — spell metadata loader (spells.csv → SpellTable)
                          (Phase F will close)

Code change is minimal — three lines of dispatch + a 12-line
CombatState method with a typed event for future killfeed UI.

818 tests passing (+1 KillerNotification).
