fix: resolve rebase conflicts and fix TC39 decorator migration issues

- Resolve merge conflicts in convertShaders.ts and tsconfig.build.json
- Add useDefineForClassFields: false to prevent class field override issues
- Add 'declare' to type-narrowing _effectWrapper overrides in 18 PostProcess
  subclasses to prevent TC39 decorator lowering from emitting void 0 assignments
  that overwrite parent constructor values
- Rename getEditableProperties/getSmartFilterEditableProperties to PascalCase
  per repo naming convention
- Add eslint-disable for internal double-underscore metadata keys
- Fix test assertion in decorators.test.ts (property stored under key name, not
  sourceName)
- Add Symbol.metadata polyfill to vitest.setup.ts for Node.js compatibility
- Fix missing curly braces in xml.interfaces.ts
- Update customShaderBlock.test.ts: className is empty string with TC39
  decorators (no target available in decorator context)
