cuere 0.1.0

Added

• QRMatrix encoding layer over segno (error level L by default, no
  error-boost, quiet zone baked in); its .modules grid is the public
  raw-matrix accessor.
• Renderers: half (Claude-Code-style Unicode half-blocks), block
  (double-width full blocks), ansi (forced black-on-white colors).
• High-level render() / show() / fits() with optional Micro QR and
  error-boost, terminal width/height fit checks, and NO_COLOR/tty-aware
  ANSI fallback.
• Rich renderable cuere.rich.QRCode with exact measurement.
• optimize_uri() — lossless uppercase optimization for fully-lowercase
  bitcoin:/lightning: (bech32) wallet URIs to reach QR alphanumeric mode.
• typer CLI: cuere [DATA | --input FILE] with --mode, --invert,
  --border, --error, --micro, --boost-error, --optimize-uri,
  --check-width/--no-check-width, --force.
• AGENTS.md and .github/copilot-instructions.md with project conventions
  and review guidelines for AI review agents (Codex, GitHub Copilot).

Changed

• NO_COLOR disables ANSI output whenever the variable is present, regardless
  of its value (including empty), per the no-color.org spec.
• The CLI strips only trailing newlines from stdin (rstrip("\r\n")),
  preserving intentional payload whitespace.
• The release SBOM excludes dev dependencies (uv export --no-dev).

Fixed

• An invalid border or render mode raises CuereError rather than leaking
  a bare ValueError, keeping the public exception contract consistent.

Security

• OSV-Scanner findings fail CI; the coverage-comment workflow_run job is
  restricted to same-repository pull-request runs; the gitleaks allowlist is
  scoped to a single test file; scripts/audit.py subprocesses have a timeout.
• Release publish routing uses anchored version matching (not substring) to
  choose PyPI vs TestPyPI, so it cannot misroute on incidental tag/branch text.
• Release builds publish via PyPI trusted publishing (OIDC) with sigstore
  signatures, SLSA provenance, PEP 740 attestations, and a CycloneDX SBOM.
