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.

Records session start/end, conversation messages, tool calls, and
errors via better-sqlite3, hooked into RealtimeSession's existing
choke points so no client-side changes are needed. Also fixes a
pre-existing gap where an upstream-initiated disconnect only forwarded
session.closed to the browser without ever calling close(), so no
session end time was ever recorded for that path.
