Update root and per-directory AGENTS.md files to reflect the current
state of the codebase: collection inventory, RBAC registry, base
management, personnel pages, training minigames, Discord bot transfer
and evaluation-reminder flows, banking currency config, migration
wrapper, and Playwright/Vivaldi e2e details.
Sends one-shot DMs once a mission is evaluable asking members to rate their leadership (and leaders to rate subordinates), gated by a new evaluationRemindersSentAt marker on Missions with its migration. Adds the /remind-evaluations staff command (manual trigger/sweep) and DISCORD_EVALUATION_POLL_MS config; updates bot and root docs.
