Function resolve_default_max_steps 

pub fn resolve_default_max_steps() -> usize

Resolve this deployment’s step-budget baseline.

POLYCHROME_AGENT_MAX_STEPS when set (and parses), else the crate’s internal default cap. A malformed or unset env var falls back to the default rather than failing the turn.

This is the same baseline this crate’s turn loop falls through to when RunTurnOptions::max_steps is unset. Exposed publicly so a caller that must pre-compute a budget BEFORE constructing RunTurnOptions — e.g. capping it against an edge-authored IngressDirective.budget_cap (#68), which can only LOWER the resolved budget, never raise it — reads the exact baseline the turn would otherwise resolve, without duplicating the env parse.
