Rebase regen baseline: regenerate all languages from current runtime schema

Regenerate generated RPC/session-event code for ts/csharp/python/go/rust
from the current runtime contract schema (runtime main + llm inference
callbacks). The opaque-json fields (e.g. SQLite bind params) are now typed
as `unknown` since the Rust contract emitter drops the `type` annotation
on `x-opaque-json` fields.

Update normalizeSqliteParams to accept the opaque `unknown`-valued param
map and validate each value at runtime (string/number/null), narrowing
safely at the boundary instead of casting.
