/**
 * AutoKap Engine — version axes (pure constants, safe on any runtime).
 *
 * Kept free of Node-only imports (no `node:module`/`package.json` reads) so it
 * can be pulled into the schema validation chain that the web app bundles. The
 * npm package version lives separately in version.ts (`APP_VERSION`).
 *
 * Two axes, both decoupled from the npm package version and from each other:
 *
 * - `CURRENT_PROGRAM_SCHEMA_VERSION` (FORM): the shape of an `ExecutionProgram`.
 *   Drives migrate-on-read (program-migrations.ts). A monotonic integer bumped
 *   whenever the program FORM changes in a way that needs a `migrate_vN→vN+1`
 *   function. Programs with no `programSchemaVersion` are treated as v0 (oldest).
 * - `ENGINE_VERSION` (SEMANTICS / PROVENANCE): the version of the runtime engine.
 *   A monotonic integer bumped by hand whenever the engine's runtime semantics
 *   meaningfully change (e.g. a new wait model ships) — NOT a per-opcode switch:
 *   the engine always applies the current semantics to every program. Stamped on
 *   each run purely for debug ("which engine produced this screenshot").
 *
 * Both are orthogonal to `ExecutionProgram.programVersion`, which is a CONTENT
 * revision counter bumped only by the healer (see program-patcher.ts).
