What was wrong

codefly generate client writes typescript/package.json and python/pyproject.toml from a scaffold that says 0.0.1, once (writeFileIfMissing), and never updates the version again. The library's own version, the value library.codefly.yaml records, never reached them. Live example: obin-ai/module-document-store clients/library.codefly.yaml says version: 0.1.14 (producer codefly/documents@0.1.14), while clients/typescript/package.json says "version": "0.0.1", which is what gets published.

Fix

• libraryVersion(output, entries) is the one source of the library's version. It is the logic writeLibraryManifest already had: for a single contract, the producer's declared version (the composed module package's, or the local service's); for an aggregate, the existing top-level version. It is computed once per run and used for the manifest and for every language.
• stampPackageVersion runs after each language generates:
  • TypeScript: package.json's top-level "version" member is found by walking the JSON tokens, and only its value bytes are replaced. Formatting, key order and hand-edits stay byte-for-byte; a nested "version" key is never touched.
  • Python: pyproject.toml's version = "…" project line, in place, the same way ensurePythonDependencies already edits that file.
  • Go: nothing to set; its version is its tag.
  • A library with no version is refused with a reason ("the library declares no version") instead of being written empty.

No new input or flag: the version is what the module already declares (Codefly generates every value).

Tests

• pkg/generators/client_version_test.go (ungated):
  • the scaffold gets the library version, and a later run moves it again
  • a compact, hand-edited package.json with a nested "version" keeps every other byte
  • pyproject.toml with a hand-added section keeps it
  • an empty version is refused by name
  • Go is a no-op
  • libraryVersion returns the producer's version
• cmd/generate/client_test.go TestGenerateClientPreservesHandEditedFiles (gated, CODEFLY_GENERATE_QUALIFY=1): after a regenerate, package.json's version equals library.codefly.yaml's and is not 0.0.1. Ran locally: PASS. With the stamp call removed it FAILS: package.json version = 0.0.1, library.codefly.yaml version = "0.0.0".

Classification

Fix, at the place that writes the package manifests. Reused: the library-version rule writeLibraryManifest already applied, and the in-place edit pattern of ensurePythonDependencies. Not done: the local-service fallback 0.0.1 in resolveLocalSource (a service that declares no version) is unchanged.

Not verified: the rest of the gated cmd/generate qualify suite; CI does not run gated tests.
