engine: `try_load_source_map` silently swallows all errors including I/O failures

[Timi16]

File: src/debugger/engine.rs — DebuggerEngine::try_load_source_map

Any error from source_map.load() is discarded with Err(_) => { self.source_map = None; }. A user who passes a truncated or wrong WASM file gets no feedback about why source locations are unavailable.

Proposal: Emit a tracing::warn! with the error message so that RUST_LOG=debug users can diagnose the issue.
