/**
 * #538: the office-hours founder-resources pitch takes no for an answer.
 *
 * The reporter found that memory instructions telling the agent to stop
 * showing the 34-resource pool kept being overridden on every update. The
 * fix is a config key — `founder_resources` — that session context cannot
 * override: `false` skips the entire section silently, forever, until the
 * user re-enables it.
 *
 * Pins: (1) the config key's default, persistence, and validation through
 * the real bin/gstack-config subprocess; (2) the generated section gates on
 * the key BEFORE any resource content; (3) the opt-out write is verified
 * before the skill may promise "never again" (R6 — a failed write must not
 * produce a false promise).
