@workflow/builders@4.0.5 crash on unicode-escape identifiers

[hugo082]

The crash is in @workflow/builders@4.0.5 workflow-graph extractor. It bundles your workflow modules and then re-parses the bundle with swc — but unicode-escape identifiers in the bundle are being double-escaped (\u00C6 → \u00C6), which swc rejects as an invalid identifier.

Impacted: @workflow/builders@4.0.5
Failure Root cause: https://npmx.dev/package-code/radashi/v/12.9.0/dist%2Fradashi.js#L1768
