`SelectFrom`, `UpdateTable` exports for `tsconfig - "declaration": true`

// `SelectFrom` and `UpdateTable` are kysely's internal query-creator return
// helpers — not exported from the kysely root. They must be named here
// explicitly because this project builds with `declaration: true` and the
// inferred return types are not nameable in the emitted .d.ts (TS2883).
// Re-verify these paths on any kysely upgrade (PLAN-txh-handle §11.3).

/**
 * The exact query surface the service/repo layers may use. `commit`,
 * `rollback`, and `savepoint` are deliberately NOT part of it: only the
 * edge (controller / middleware / scheduler job) may end a transaction.
 *
 * If a future feature needs another entry point (e.g. `deleteFrom`), add a
 * delegating method here — that is the deliberate design point where the
 * lower layers' surface grows. Never expose lifecycle methods.
