feat: add quickjs middleware (#261)
* feat(quickjs): add @langchain/quickjs — sandboxed JS/TS REPL with PTC, env isolation, and RLM support
* chore: split changesets into quickjs minor + deepagents patch
* refactor(quickjs): remove env/secrets, lazy runtime, buffered writes, fix thread_id propagation
- Remove entire env/secrets system (EnvVarConfig, EnvConfig, secretRef, injectEnv, blockEnvLeaks, checkEnvAccess, generateEnvPrompt)
- Lazy-load QuickJS WASM runtime on first eval via ensureStarted()
- Buffer file writes in pendingWrites[], flush after eval via flushWrites(backend)
- Make ReplSession.getOrCreate() synchronous (runtime init deferred)
- Add toJSON()/fromJSON() for session serialization
- Fix thread_id propagation: move session creation from wrapModelCall (which lacks configurable) to tool handler (which has config.configurable.thread_id)
- Remove dead starting map from ReplSession
- Add integration test verifying REPL state persists across js_eval calls
- Add thread_id propagation unit tests
- Remove secret-env-agent example
- 68 unit tests + 1 integration test passing, types clean
