feat(connectors): add moss-connector-zeroentropy

[HarshaNalluru]

What

A new data connector, moss-connector-zeroentropy, that migrates a ZeroEntropy collection into a Moss index. Follows the established moss-data-connector/_template pattern exactly (same shape as the Supabase/MongoDB/DynamoDB connectors).

from moss_connector_zeroentropy import ZeroEntropyConnector, ingest

source = ZeroEntropyConnector(collection_name="my_collection", api_key="...")  # or ZEROENTROPY_API_KEY
await ingest(source, project_id="...", project_key="...", index_name="my_collection")

How it works

• ZeroEntropyConnector.__iter__ walks documents.get_info_list (an auto-paginating cursor) and yields one moss.DocumentInfo per document via a mapper.
• Default mapping (path -> id, parsed content -> text, metadata -> metadata) means a whole collection migrates with no mapper; pass mapper= to customize.
• The list endpoint returns metadata only, so content is fetched per document via documents.get_info(..., include_content=True). Documents that never parsed (no content) are skipped rather than indexed empty.
• ZeroEntropy metadata is typed Dict[str, str | list[str]]; the connector coerces list values to strings (Moss requires Dict[str, str]).
• path_prefix= scopes the migration; include_content=False migrates metadata only.

Testing

• tests/test_zeroentropy.py — 9 mocked unit tests, all passing (default/custom mapper, skip-empty-content, include_content=False, path_prefix, auto_id, empty collection, metadata coercion).
• tests/test_integration_zeroentropy_moss.py — skippable live round trip (ZeroEntropy → Moss → query → delete), gated on ZEROENTROPY_API_KEY / ZEROENTROPY_TEST_COLLECTION / MOSS_PROJECT_ID / MOSS_PROJECT_KEY.
• Verified against the installed zeroentropy 0.1.0a11 SDK by introspection: method names, keyword params (collection_name, path, include_content, path_prefix), the SyncGetDocumentInfoListCursor return, and every response field the connector reads all match.

Also

• publish-moss-connector-zeroentropy.yml (mirrors the other connectors' publish workflows).
• Row added to packages/moss-data-connector/README.md.

CI is green (python-lint + python-sdk-test pass under the pinned ruff from #480).

Pull request overview

Adds a new Python data connector package under packages/moss-data-connector/ to migrate a ZeroEntropy collection into a Moss index, consistent with the existing connector template and publish workflow patterns used elsewhere in the repo.

Changes:

• Introduces moss-connector-zeroentropy package with ZeroEntropyConnector + ingest() helpers for collection migration.
• Adds mocked unit tests and a skippable live integration test (ZeroEntropy → Moss → query → delete).
• Wires the connector into the mono-repo docs and adds a dedicated publish workflow.

Codex review

The connector implementation is mostly coherent, but the release workflow has a release-integrity hazard around version reuse.

[github-actions]

BLOCKING ```yaml
twine upload --skip-existing packages/moss-data-connector/moss-connector-zeroentropy/dist/*

`--skip-existing` makes a reused version look like a successful publish, so this job can still tag the current commit even when PyPI already contains artifacts built from a different commit. Remove `--skip-existing` and fail on existing versions, or pre-check the tag/PyPI version and only skip when you can verify the existing artifacts correspond to this exact commit.
