v0.5.0

• Add compact YAML/JSON drafts: bioevidence build and build_record() derive identifiers,
  group evidence lines and hash named local files, without supplying scope, method, times
  or review decisions. Strict parsing rejects unknown, missing and out-of-choice fields.
• Add bioevidence draft-schema and draft_json_schema(): a per-profile JSON Schema for
  drafts, e.g. for LLM structured output.
• Add a composite GitHub Action that validates records or drafts in pull requests, with a
  job summary, file annotations and count outputs.
• Add a Colab quickstart notebook and draft examples.
• Export build_record, load_draft, draft_json_schema and validate_record from the package root.
