Nuzo 0.8.0

Added

• CI now gates the canonical recall benchmark, the historical capture baseline,
  and the current bounded capture relationship profile on every pull request.
• A published optional-semantics smoke validates registry-installed fallback,
  optional peer installation, local sidecar rebuild, and semantic/hybrid recall
  against exact published packages.
• The optional-semantics benchmark now includes a medium-store profile with
  scoped status, fallback, cold and warm hybrid recall, peak RSS, canonical row
  counts, vector row counts, and authorized vector count gates.
• The NUZO-37 host canary proves the generated Codex and Claude Code artifacts
  deliver the same user:default autoload instruction across fresh hook
  invocations while preserving the untrusted-memory boundary.
• An optional native host canary installs the Codex artifact through a temporary
  local marketplace and validates the Claude Code artifact with the npm
  distributed Claude Code CLI.

Changed

• Release validation now explicitly includes the medium-store semantic gate,
  the NUZO-37 host canary, and a post-release issue-hunting pass for focused
  roadmap follow-up.
• Repository layout documentation now states that tools/ is versioned
  repository automation, not a runtime npm package surface.

Fixed

• MCP runtime shutdown now awaits optional semantic provider disposal before
  closing the SQLite database or exiting on signals.
• Scoped semantic index status now queries only authorized vector scopes in SQL
  instead of loading all sidecar vectors and filtering unrelated scopes in
  JavaScript.
• Host-hook fixtures now use explicit /example/... paths instead of
  host-looking /opt/... paths.
