Copilot review overview

🔵 Needs a closer look

Unresolved moderate issues remain around TRACE serialization error handling and invalid logging-level fallback behavior.

Review effort: Lite
Findings: None

What changed in this PR

Adds configurable ERROR/WARN/INFO/DEBUG/TRACE logging, including TRACE-level JSON-RPC payload dumps and configuration UI support.

Changes:

• Adds shared severity filtering and runtime configuration updates.
• Routes WebSocket and preprocessor logs through the shared logger.
• Updates interfaces, documentation, tests, and package scripts.

File	Summary
src/​utils.ts	Integrates configured logging. Nit (1 vote): add fallback tests for missing/invalid values resetting logging to INFO.
src/​test/​suite/​logger.test.ts	Adds logger behavior tests.
src/​synchservice.ts	Uses the shared WebSocket logger.
src/​shared/​logger.ts	Implements filtering. Moderate (1 vote): WARNING should be removed or documented; invalid values must fall back to INFO.
src/​server/​nodehost.ts	Adds trace logger support.
src/​scriptsync.ts	Routes preprocessor logs through the shared logger.
src/​interfaces/​configinterface.ts	Adds the logging configuration key.
src/​extension.ts	Initializes logging configuration.
README.md	Documents logging settings.
packages/​sl-script-preprocessor/​src/​interfaces.ts	Extends the preprocessor logger interface.
packages/​sl-ide-ws-client/​src/​jsonrpcclient.ts	Adds TRACE payload dumps. Three moderate findings (1 vote each): request, notification, and response serialization occur before the existing error boundary and can throw for non-serializable values.
packages/​sl-ide-ws-client/​src/​events.ts	Extends the WebSocket logger interface.
package.json	Adds the logging setting and test updates.
doc/​USER_GUIDE.md	Documents logging configuration.

Preserve string-only WsLogger callback compatibility

packages/​sl-ide-ws-client/​src/​events.ts:59

Changing the existing debug/info/warn/error callback parameters from string to string | (() => string) is a source-breaking change for hosts that implement WsLogger with string-only callbacks. The new call sites use thunks only for trace, so keep the existing four signatures string-based and use the thunk union only for the new trace callback (or provide an adapter/overload).

Preserve string-only PreprocessorLogger callback compatibility

packages/​sl-script-preprocessor/​src/​interfaces.ts:40

Changing the existing logger callbacks from string to string | (() => string) breaks existing PreprocessorLogger implementations whose methods accept only strings. None of the existing debug/info/warn/error call sites need lazy thunks; retain their string signatures and reserve the thunk union for the new trace callback, or add an explicit compatibility adapter.
