v0.81.0-beta.5

Added

• Added deployable-install diagnostics and an installed-artifact verifier covering bundled dependencies, extensions, /reload, /new, and profiles.

Changed

• Changed install:local to install the staged bundled tarball; source linking moved to link:dev.
• Staged npm releases now use a temporary candidate dist-tag and promote final tags only after six-platform installed-runtime verification.

Fixed

• Fixed pi-opencode-bridge registration disappearing when /reload or /new creates a fresh extension runtime.
• Rejected direct workspace packing that omits the three bundled private runtime packages.
