Pull request overview

Implements a new compilation.hooks.assetPath hook intended to let plugins transform resolved asset output paths during filename/path rendering (webpack SyncWaterfallHook-style), wiring it through the Rust core compilation path rendering and the JS hooks adapter layer.

Changes:

• Add Compilation.hooks.assetPath (SyncWaterfallHook) on the JS Compilation wrapper and register it through the JS tap bridge.
• Call the new asset_path hook from Rust compilation path rendering helpers (get_path* / get_asset_path*).
• Add JS and Rust tests covering basic invocation/return-value behavior and some PathData rendering cases.

@yashwanth195 thanks for contribution, but this hook will cause deadlock issue in Rspack, related to #3642, you can try to call compilation.getPath in your test case and see whether it will cause deadlock
