MidnightNameplates 0.11.2 - Cast Target + Interrupt State

NEW
- Cast target text with ALWAYS / SELF_ONLY / NEVER.
- ARROW / COLON / BRACKETS formats.
- Separate self-target color.
- Interrupt state text: KICK / LOCKED.
- Separate colors/font size.
- UNIT_TARGET refresh while casting.
- Safe secret-value checks.

TEST
1. Enemy casts at another player -> target name appears.
2. Enemy casts at you -> self color.
3. SELF_ONLY hides casts targeting others.
4. KICK vs LOCKED reflects interrupt state.
5. Cast stop clears both labels.
6. Phase 11.1 HIGH/CRITICAL cast alert still works.
7. No Lua/taint/secret errors.
