MCP tool results can include ImageContent blocks (screenshots from Playwright/Blockbench/Puppeteer etc). The tool result handler only extracted block.text, so image blocks were silently dropped and the agent saw an empty or text-only response — losing the actual payload. Add _cache_mcp_image_block() that base64-decodes the block, validates the bytes via gateway.platforms.base.cache_image_from_bytes (which sniffs for PNG/JPEG/WebP signatures and rejects non-images), writes to the shared `~/.hermes/cache/images/` dir, and returns a MEDIA:<path> tag. The handler appends that tag to the result parts so downstream gateway adapters render the image inline. Logs and drops on malformed base64 / non-image payload rather than raising — a single bad block shouldn't kill the tool call. Distilled from #17915 (c3115644151) and #10848 (gnanirahulnutakki), both too stale to cherry-pick (branches diverged enough to revert dozens of unrelated fixes). Went with #10848's approach of plumbing through Hermes' existing MEDIA tag / cache_image_from_bytes infrastructure rather than #17915's raw tempfile path, because it integrates with the remote-backend mount system and messaging adapters that already handle MEDIA tags natively.
