refactor(address-space): typed event emitters + biome conformance

Introduce a typed-event-emitter contract for the address-space class
hierarchy, and apply Biome 2.4.14 across the repo.

Typed events (address-space-base):
- Replace `declare class X extends EventEmitter` declarations with
  `interface X<T extends ListenerSignature<T>> extends ITypedEventEmitter<T>`
  for BaseNode, UAVariable, UAObject, UAMethod, UAObjectType,
  UAVariableType, UAReferenceType, UADataType, UAView.
- Add per-class event maps: BaseNodeEvents, UAVariableEvents,
  UAMethodEvents, etc., each extending the parent map.
- Introduce `ListenerSignature<L>` self-referential constraint and
  `ITypedEventEmitter<T>` so listeners are checked against the event
  map at compile time. `TypedEventEmitter` aliases Node's EventEmitter
  so listeners observe `this === <emitter>` (the previous
  composition-based wrapper broke that contract).
- Add ua_base_event_ex.ts (UABaseEventEx, UABaseEventEvents).

Tooling:
- Add biome.json (formatter + `useImportType` linter rule, lf line
  endings, 4-space indent, lineWidth 132, double quotes, no trailing
  commas) and @biomejs/biome 2.4.14 devDep.
- Set tsconfig.common.json `types: ["node"]`.

Mechanical biome cleanup across ~325 files in packages/* and tests:
- Convert type-only imports to `import type`.
- Use `node:` protocol for builtin imports (e.g. `node:events`).
- Reorganize/sort imports.
- Prefer `Number.isFinite` over global `isFinite`, `**` over
  `Math.pow`, prefix unused parameters with `_`.
