v0.2.2

SDK refactor — method registry, protocol adapters, modular architecture

Breaking changes

• message.history now requires agentToken parameter
• room.list no longer returns id field

New

• JoinCloudServer class with method(), before(), after() for extensible method registration
• MethodRegistry with protocol-agnostic method declarations and before/after processors
• Protocol adapters: A2A (routes, adapters, agent-card, push), MCP (server, adapters)
• Store interface for pluggable storage backends (SQLite default)
• SDK exports for building custom servers: createDefaultServer, createA2aRoutes, createAgentCardRoutes, startMcpServer, setBotStore, etc.
• Dynamic method table generation from registry (replaces static markdown files)
• Modular website: HTML templates, CSS files, static asset serving

Fixed

• Security: execSync → execFileSync in git operations
• Inlined validateEndpointUrl (removed security.ts)
