Pictovap 0.7.6 — contributor and adapter workflow

Pictovap 0.7.6

Pictovap 0.7.6 aligns the published package with the current contributor and
adapter workflow.

Highlights

• Standalone Pixabay and Wikimedia provider references now perform real response
  mapping with mocked, credential-free contract tests.
• CI installs and tests standalone provider and renderer packages, verifies
  plugin discovery, runs adapter conformance checks, and builds wheels.
• pictovap scaffold provider|cms produces installable, lint-clean starter
  packages with entry-point metadata and contract tests.
• The repository includes a pinned, automatically validated OpenSSF Criticality
  Score measurement workflow.
• Contributor setup documents the Python 3.10+ requirement and does not imply
  that API credentials are needed for the demo or unit suite.

Verification

• 239 unit tests passed in a clean Python 3.11 environment.
• Provider and CMS scaffolds passed install, test, discovery, doctor, and
  default flake8 checks.
• Main-branch CI, CodeQL, and Scorecard passed before tagging.

Pictovap remains early-stage infrastructure. This release does not claim broad
downstream adoption or independent publisher validation.
