MeTTa TS 1.3.0

MeTTa TS 1.3.0

MeTTa TS 1.3.0 moves the standard libraries and the debugger engine out of the
core into their own packages. The interpreter behaves exactly as in 1.2.0: the
conformance oracle is byte-identical and every library returns the same results.
This is a structural release, so there are no new language features.

@metta-ts/libraries

The eight standard libraries (vector, roman, combinatorics, patrick,
datastructures, spaces, nars, pln) moved out of @metta-ts/core into a
new @metta-ts/libraries package, one folder and one .metta file per library,
so the engine no longer ships library source it does not run.

@metta-ts/node, @metta-ts/hyperon, and @metta-ts/browser depend on the new
package and register it when they load, so (import! &self pln) and the other
library imports keep working with no change. The one behavior change is that bare
@metta-ts/core no longer resolves the libraries on its own. A program run
through runProgram from core alone registers them first:

import { registerLibraries } from "@metta-ts/libraries";
registerLibraries();

The libraries are ports of Patrick Hammer's PeTTa lib/lib_*.metta set, with
roman from Roman Treutlein's PeTTa prelude; the extraction now credits them.

@metta-ts/debug

The metta-debug engine moved into a new @metta-ts/debug package. It holds the
execution-trace summary behind why and the explainCall, collectTrace, and
summarize helpers, depends only on @metta-ts/core, and uses no Node APIs, so
an editor or tool can drive it directly. The metta-debug command still ships in
@metta-ts/node and works exactly as before, now a thin wrapper over the shared
engine.

Verification

Checked on Linux with Node and pnpm.

• Build, type check, lint, and format checks pass across all twelve packages.
• pnpm test passes: 1,218 tests across 126 files, with 38 optional live
  integration tests (7 files) skipped.
• The oracle passes all 23 corpus files, byte-identical to 1.2.0: the extraction
  moves the library source without changing it.
• The repository is REUSE 3.3 compliant.

Packages

All public packages use version 1.3.0:

npm install @metta-ts/core@1.3.0
npm install -g @metta-ts/node@1.3.0

The standard libraries and the debugger engine are available on their own:

npm install @metta-ts/libraries@1.3.0
npm install @metta-ts/debug@1.3.0
