Add KillAura option to ignore named mobs

[zyckk4]

KillAura can currently attack name-tagged mobs kept near the bot. Add killAura ignoreNamedMobs on/off (default: off) to exclude non-player entities with a custom name before evaluating hostile, neutral, or custom targets. Player targeting and existing configurations retain their current behavior.

The filter checks the presence of the optional custom-name metadata, independent of name visibility, and reflects later name additions/removals. Command help, status output, and generated wiki documentation include the setting. This filters direct targets; server-side sword sweeping damage is unaffected.

Closes #333.

Validation

• Added 14 passing regression cases covering hostile/neutral aggression, custom targets, visibility, empty/removed names, player targeting, defaults, serialization, and the command/status output.
• Complete local JDK 25 build passed: 93 tests passed, 1 skipped (ConnectIntegTest, Docker unavailable); executable JAR and command documentation generated.
• Windows qualification: the ordinary gradlew.bat build run hit a temporary-JAR deletion failure in the existing SharedApplicationClassLoaderTest.failedTransformationFallsBackToOriginalBytesAndDisablesTransformers teardown. The successful full run used a local, uncommitted init script setting junit.jupiter.tempdir.cleanup.mode.default=NEVER on test tasks; all test assertions remained enabled. No workaround or unrelated loader changes are included in this PR.
• git diff --check passed. Live Minecraft-server behavior has not been tested.
