Upgrade Bun's self-reported Node.js version from v24.3.0 to v25.3.0.

Changes:
- Update NODEJS_VERSION to 25.3.0
- Update NODEJS_ABI_VERSION to 141 (NODE_MODULE_VERSION)
- Update V8 version to 14.1.146.11 (from 13.6.233.10)
- Update libuv version to 1.51.0 (from 1.48.0)
- Update V8 Isolate root indices to match V8 14.1:
  - kUndefinedValueRootIndex: 4 -> 0
  - kTheHoleValueRootIndex: 5 -> 1
  - kNullValueRootIndex: 6 -> 2
  - kTrueValueRootIndex: 7 -> 3
  - kFalseValueRootIndex: 8 -> 4
- Update V8 Isolate padding from 78 to 79 elements (kIsolateRootsOffset: 640 -> 648)
- Update m_roots array size from 9 to 6 elements

N-API version remains at 10 (still the latest).
