blockrunai/blockrun-mcp

blockrun_image, blockrun_video, and blockrun_music now surface the USDC cost in their result: a Cost: $X.XXXX line in the text output and a cost_usd field in structuredContent, matching blockrun_speech / blockrun_realface. Video and music report the real 402-settled amount (token-priced upstream, so 1080p/4K clips and long tracks can exceed the per-unit estimate); image uses the catalog estimate on Base and the 402 amount on Solana, each falling back to the estimate only if the quote doesn't parse. No new spend path and no change to what is charged — the figure shown is the same amount already booked to the budget ledger. Adds handler-level tests (HTTP + x402 mocked, no network/no spend). Typecheck clean, 109 tests pass, build + 18-tool stdio smoke green.
