Prototype standalone world workers for 2.2.0.0 alpha1

[SimGamerJen]

Summary

Starts the HelperProfiles 2.2 development cycle with a deliberately narrow standalone world-worker prototype, while leaving the 2.1.0.0 ModHub baseline untouched.

What this alpha adds

• per-save static world placement state keyed by permanent A-T / helper01-helper20 identity
• standalone HumanGraphicsComponent runtime instances rather than fake players or AI jobs
• AvatarSwitcher-bound PlayerStyle reuse where available, with helper-style fallback
• static NPC/idle animation parameters
• terrain-aligned placement approximately two metres in front of the local player
• persistence across save reloads
• temporary runtime despawn while the same helper is active on an AI job, followed by automatic restoration at the saved world position when the job ends
• hpWorld console commands for isolated engine testing

Test commands

hpWorld help
hpWorld status
hpWorld place [slot]
hpWorld move [slot]
hpWorld remove [slot]
hpWorld refresh [slot]

The slot argument accepts A-T, helper01-helper20, or 1-20. Omitting it uses the currently selected HelperProfiles worker.

Intentionally not included yet

• management-screen controls
• walking/pathfinding
• schedules or behaviours beyond static idle
• interactions/dialogue
• multiplayer/network replication

See docs/WORLD_WORKERS_ALPHA1.md for the initial in-game test sequence and expected alpha risks.

Do not merge until standalone human rendering, appearance loading, persistence and AI-job suppression have been validated in FS25.

Alpha1 test result: hpWorld status loaded correctly, but hpWorld place A returned local-player-unavailable. Root cause was the prototype relying on g_localPlayer / g_currentMission.player. Current FS25 PlayerSystem owns live Player instances and marks the local one with isOwner. Patched the branch to resolve the owner from g_currentMission.playerSystem.players (with SP index fallback) and to use Player:getMapPositionAndLookYaw() as the primary placement source. Added diagnostic placement-source logging for the next test.
