• Automatic main → main-empty package synchronization
• New production build, APIStatic, SSR, package, and bundle-size CI checks

APIStatic

APIStatic can now:

• Compile data/endpoint/**/*.route into browser-loadable static endpoint modules
• Generate a route manifest automatically
• Use stable logical endpoint names without manually dealing with hashes
• Support multiple operations per endpoint
• Support run.query, run.body, run.input, and run.proxy
• Validate and coerce typed input schemas
• Support defaults and optional values
• Use normal async functions, fetch(), objects, arrays, and TypeScript syntax
• Return normal values or explicit response(...)
• Throw controlled error(...) responses
• Call configured backend bridges through proxy()
• Discover endpoints with APIStatic.names(), has(), and getEndpoints()
• Automatically watch and recompile .route files during development
• Preserve the last-known-good build if compilation fails
• Publish endpoint JS + manifest atomically
• Handle lexical scopes correctly, including normal variables like const response
• Safely support compact helper[...] call syntax without corrupting arrays, strings, comments, regex, or shadowed variables
• Integrate directly with EngineAPIResolver
• Run dedicated compiler/runtime regression tests in CI

Overall: v2.5.0 focuses heavily on performance, runtime correctness, APIStatic, and making NE's documented APIs actually match the implementation.
