/**
 * Agent-facing Content capabilities. Four tools, deliberately mirroring the
 * Trading vertical's shape:
 *
 *   ContentCreate     — start a new piece with type/title/budgetUsd
 *   ContentAddAsset   — record a generated asset (image/audio/etc.) with its
 *                       cost; rejected (as normal text, not an error) if it
 *                       would breach the per-piece budget
 *   ContentShow       — dump a single piece's state as actionable markdown
 *   ContentList       — summary of every piece, newest first
 *
 * This is the surface generic coding agents can't cover: durable content
 * state with autonomous spending gating. An agent can spin up "Franklin
 * launch thread" with a $3 budget, hit DALL-E twice for hero images, blow
 * the budget, read the refusal, pick a cheaper model, and continue — all
 * without human intervention and with the project surviving to the next
 * session.
