chore: adding vue client sdk wrapper

[joker23]

Additional changes:

• modified tsconfig.json to match the rest of the monorepo

---

Note

Low Risk
New package surface and thin delegation to the existing JS client SDK; no auth or server paths, with behavior covered by unit tests.

Overview
Replaces the Vue package scaffold with a working createClient factory that wraps @launchdarkly/js-client-sdk, sets default wrapperName / wrapperVersion, and adds Vue-oriented lifecycle APIs (getInitializationState, isReady, onInitializationStatusChange with replay for late subscribers, onContextChange after successful start / identify).

Exports LDVueClient, LDVueInstance, and LDVueProviderOptions types (provider/composables still TODO). Package now depends on the workspace JS client SDK, runs Jest without passWithNoTests, and adds test tooling; tsconfig.json is updated to match other SDK packages (ES2020, bundler resolution).
