Apply SEO and metadata best practices

[mintlify]

Summary

Adds descriptive titles and unique, search-friendly descriptions across 188 documentation pages that previously had missing, boilerplate, or duplicated metadata.

Changes

• Added description frontmatter to pages where it was missing (account management, agents, files, frameworks, gateways, ipfs-101, SDK pages, x402 guides, MCP, CLI, and more).
• Replaced short/permission-tag descriptions (e.g. `org:files:write`) on every SDK reference page with content-specific summaries that mention the SDK method, what it does, and the required permission.
• Rewrote duplicate descriptions (events pages, hot-swaps pages) so each page in scope has a unique description.
• Tightened generic titles (Overview, add, list, get, etc.) into descriptive ones such as Pinata Agents overview, groups.public.add-files, and Models available on Pinata Inference, all under 60 characters.
• Added descriptions for the 12 OpenAPI operation pages whose specs don't supply one (/groups and /ipfs/swap operations on pinata-api-ipfs.yaml).
• Normalized Title: → title: on sdk/types.mdx so it's recognized as frontmatter.
• Targeted 130–155 character descriptions and verified uniqueness across all pages in scope.

Context

Triggered by the merge of #108, which added many new pages (agents, inference credits, llm-docs, x402) with minimal or missing SEO metadata.
