Module services_env 

Single source of truth for building ServicesOptions from the environment.

Previously context.rs, commands/daemon.rs, commands/tick.rs, and commands/services.rs each rolled their own (subtly divergent) services setup. This module unifies them and adds the Arcade V2 surface.

Environment variables

Var	Effect
CHAINTRACKS_URL	Chaintracks header service for proof validation
ARC_URL	Override the broadcaster URL (classic ARC, or the Arcade endpoint in Arcade mode)
ARC_MODE=arcade or ARCADE=1	Arcade V2 mode: EF-only submit, SSE status stream, push proofs
CALLBACK_TOKEN	Override the per-wallet callback token (otherwise auto-generated and persisted next to the db)
PUBLIC_CALLBACK_URL	Public HTTPS URL Arcade should POST status webhooks to (X-CallbackUrl)
TAAL_API_KEY	TAAL ARC key sent as Authorization: Bearer <key>
MAIN_TAAL_API_KEY	TAAL ARC key sent as raw Authorization: <key> (TAAL accepts no Bearer prefix)
