fix: enforce abstract length limit (<= 200 chars) and validate Databus URIs

[yush-1018]

Pull Request

Description

This PR fixes input validation gaps when creating Databus dataset metadata:

1. Abstract Length Validation: Enforces the documented maximum limit of 200 characters for artifact_version_abstract in create_dataset(), raising BadArgumentException when exceeded.
2. Databus URI Validation: Implemented validate_databus_version_uri() helper in databusclient/api/utils.py to ensure version URIs have valid HTTP/HTTPS schemes and valid path components (<BASE>/<ACCOUNT>/<GROUP>/<ARTIFACT>/<VERSION>).
3. Unit Tests: Added comprehensive test cases in tests/test_deploy.py for abstract length limit enforcement and invalid URI formats.

📝 Walkthrough

Walkthrough

create_dataset now enforces the 200-character abstract limit and validates version_id with a shared Databus URI validator. Invalid inputs raise BadArgumentException. Tests cover oversized abstracts and malformed version URIs.

Changes

Dataset validation

Layer / File(s)	Summary
Databus version URI validator databusclient/api/utils.py	Adds validation for URI type, HTTP scheme, path segment count, and empty path segments.
Dataset creation validation and tests databusclient/api/deploy.py, tests/test_deploy.py	create_dataset rejects trimmed abstracts longer than 200 characters and converts invalid version_id errors to BadArgumentException. Tests cover both validation paths.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to d9d17

The PR adds URI validation, but malformed version identifiers such as trailing-slash paths or components containing spaces can still be accepted and used to construct dataset metadata. This creates a concrete correctness risk that should be fixed before merge; deployments using path-prefixed Databus base URLs may also require owner confirmation.

Explanation

The PR addresses abstract validation in create_dataset() and adds URI validation tests. It does not address the linked issue requirement to validate the stripped abstract in cli.py, and validate_databus_version_uri() does not validate invalid characters.

- Around line 92-95: Update the URI parsing and validation in the relevant
utility function around stripped_uri and parts: preserve slash delimiters so
leading/trailing or repeated separators produce empty segments, require a valid
authority, and validate every Databus component against its allowed character
rules rather than accepting spaces or other invalid characters. Add regression
coverage for a trailing slash and a component containing a space such as “gr
oup”.
