a5d9ae8ed2- hello-world-node: wrap server startup in async main() with proper await on server.connect(transport) — fixes crash on initialize in Claude Desktop UtilityProcess runtime (closes #200) - hello-world-uv: add required mcp_config block — v0.4 schema requires it but the example omitted it, causing mcpb pack to fail - file-manager-python: convert from broken v0.1/python to v0.4/uv — the old manifest had privacy_policies on v0.1 (schema violation), used command "python" (ENOENT on macOS), and had no bundled deps. Now uses UV runtime with proper mcp_config (closes #47, closes #72) - Graduate UV runtime from experimental across docs and schema comments - Bump DEFAULT_MANIFEST_VERSION from 0.2 to 0.3 All three examples verified: pack succeeds, server responds to MCP initialize over stdio, tools/list returns expected tools.
