chore(launch): product hunt launch assets

[evantahler]

Summary

• Product Hunt launch assets in launch/: 4 gallery slots (SVG + PNG), tagline, description, maker comment, topics, runbook
• Rename PROCESS_NAME default from actionhero-server to keryx in .env.example files so the example app reports a proper name on bun dev and in MCP tool calls

Gallery

• Slot 1 (thumbnail): one action class → five transports
• Slot 2: quickstart terminal — bunx keryx new my-app → bun dev → HTTP/WS/MCP/OpenAPI/workers/db
• Slot 3: real Claude Desktop screenshot calling Keryx MCP tools with OAuth 2.1
• Slot 4: VS Code showing backend MessagesList action → frontend ActionResponse inference
• Slot 5 (demo gif): intentionally skipped for first launch

Copy

• launch/tagline.md: "The Fullstack TypeScript Framework for MCP and APIs"
• launch/description.md: 260-char PH description
• launch/maker-comment.md: ~370-word first-comment script that leads with the MCP duplication pain
• launch/topics.md: Developer Tools, Open Source, AI, GitHub
• launch/runbook.md: T-7 / T-3 / T-1 pre-launch timeline, launch-morning playbook, comment-response templates, X/LinkedIn/HN cross-post copy

No version bump

Pure launch-marketing assets — nothing in the published package surface changes. .env.example default tweak is config-only.

Test plan

• Open each PNG and verify it renders correctly at PH thumbnail dimensions (1270×760)
• Sanity check tagline + description fit within PH character limits
• Sanity check the maker comment markdown renders correctly when pasted into PH's comment field
• Verify bun dev in example/backend reports name: "keryx" in /api/status after pulling the .env.example change locally
