v1.1.0

Added

• CITATION.cff: author identity (Nathan Riley + ORCID) and a
  scaffolded identifiers: block ready for the Zenodo concept DOI.
• CONTRIBUTING.md.
• Docusaurus build job in CI.

Changed

• Panic surface eliminated (WP17). Reader mutex locks now
  map_err(...) into CorruptFrame-style errors with a "mutex
  poisoned" message, PyO3 mutex locks raise PyRuntimeError, and
  chunks_exact(4) retains a localized #[allow]. Library crate
  carries #![cfg_attr(not(test), warn(clippy::unwrap_used, clippy::expect_used))].
• Project renamed from OpenTDF to OpenTimsTDF; documentation,
  scripts, and PyPI metadata updated accordingly.
• Manifest hygiene (WP13): homepage set to https://sigilweaver.app
  and documentation link added.
• README badge block unified across the Sigilweaver portfolio.
