v0.1.4

Changed

• State contract is now explicitly shell-owned: the shell team maintains it and reviews all change requests from MFE teams
• Defaults (initialState) are the shell's responsibility — the contract only exports the type shape (AppState) and key names (APP_STATE_KEYS)
• APP_INITIAL_STATE removed from the contract — defaults live in the shell's app.config.ts alongside provideNgxMfeBroker()
• Updated diagram and non-monorepo section to reflect shell ownership model
