Stenobar 1.0.0-beta.6

Added

• stenobar:// URL scheme and a JSON library index for external integrations (e.g. a Raycast extension): open the library / a recording / project / Thoughts inbox / settings, and fire record-toggle, dictate, thought-capture, and marker the same way the global hotkeys do. A versioned index.json snapshot of recordings + thoughts is refreshed on every change so external tools can search without touching SwiftData. “Copy Link” actions produce stenobar://recording/<uuid> links. See docs/URL-SCHEME.md.
