Centralizes env parsing/validation into a single loadConfig() (config.ts),
replacing scattered process.env reads across server.js and dev-plugin.ts and
making dev fail fast on a missing OPENAI_API_KEY the same way prod already
did. Analytics gains a master on/off switch (a new NoopAnalyticsRecorder,
selected when ANALYTICS_ENABLED=false) plus independent category toggles for
messages/tool calls/events, so a deployment can control what gets logged
without writing a custom recorder. Session persona (model/instructions)
moves out of the core defaults.ts into project-owned persona.ts, mirroring
the existing tools.ts split and fixing a prior inconsistency where a
branched project was expected to hand-edit a core file. Client tool timeout,
token TTL, model override, and default voice are now env-configurable
instead of hardcoded constants.

Extends the realtime session protocol with tool.call/tool.result/response.trigger
so the model can invoke functions that run either on our server or, relayed
through the session, in the browser (e.g. DOM interaction) — a single
outstanding-call counter lets a turn mix both without racing the model's
continuation. createToolRegistry enforces at startup that a client-only tool
can never accidentally be backed by server logic.
Also introduces a project/ namespace alongside core/, server/core/, and
client/core/, for code specific to whichever client project branches from
this template. Core never imports project; the two composition roots
(server.js, vite.config.ts) do the merge instead, so template updates can
still be pulled into a branched project without touching core files.

Provider-agnostic session layer for the base project: a shared client/server
wire protocol, a RealtimeProvider adapter interface, and an OpenAI Realtime
implementation of it, wired through a WebSocket relay (browser <-> our
SvelteKit server <-> OpenAI) so the API key never reaches the browser and
future providers/pipelines can be added without touching client code.
Switches the adapter to adapter-node and adds a custom server.js + dev-mode
Vite plugin, since SvelteKit has no native WebSocket support yet.
