Fixes Double Copy of WASM

[Step7750]

TLSN Wasm is ~16MB, current setup was copying the file twice into the build.

This change switches to prevent a hash rename for tlsn_wasm_bg.wasm while still copying the .js files.

---

Note

Low Risk
Build-only webpack configuration change scoped to how a single WASM asset is emitted and copied.

Overview
Stops bundling/copying @csfloat/tlsn-wasm’s tlsn_wasm_bg.wasm twice by handling it via a dedicated webpack asset/resource rule that emits a stable tlsn_wasm_bg.wasm filename (no hashed rename).

Updates the CopyPlugin patterns to copy only the package’s .js files (and snippets/), removing the previous *.{wasm,js} copy step for the WASM binary.
