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.

Adds docs/ARCHITECTURE.md (module layering, foundational infra decisions,
subsystem index) and docs/REALTIME_SESSION.md (the WS relay design, the
provider extensibility seam, the trust boundary, SvelteKit's WS plumbing
workaround, and the OpenAI event-naming gotcha found via live testing).
Restructures AGENTS.md around orientation, conventions, and process, and
establishes documentation as part of the same change as the work itself
rather than a follow-up pass.
