Budget hunt supplies, prioritize Exura, and avoid transit fights

[adrunkhuman]

• Prefer safe hunts whose estimated potion consumption fits the hunt-duration budget after reserving travel and emergency supplies. Rank fitting candidates by XP; when none fits, prefer the lowest expected potion consumption, then XP. Reconcile the preference after concrete route validation.
• Prioritize learning Exura when legally available and affordable, retaining emergency potion and cash reserves rather than requiring a full ten-potion restock. Recheck reserves before payment.
• During transit, including ordinary depot returns, ignore optional attackers even in crowds. Prefer detours; allow confirmed route blockers one five-second, no-chase attempt per transit episode. Navigation replans and intermediate arrivals do not renew the allowance. Preserve deliberate hunting and healing priority.
• Add explanatory selection telemetry and regression coverage for supply budgets, Exura affordability, crowd transit, and bounded blocker combat followed by resumed looting.

Limits and follow-up

• Consumption estimates remain uncalibrated. This does not establish sustainable level 8–20 progression.
• The soak exposed a two-spawn Troll pocket whose adjacent patrol points keep the bot near the spawns, preventing normal replenishment. The atlas still offers such pockets as standalone hunts; respawn-compatible hunt viability remains follow-up work.
• Expected loot profit and excluding isolated tiny pockets from standalone hunt selection are deferred. Potion thresholds and seed funds are unchanged.
