GCD Usage 0.4.1

GCD Usage 0.4.1 adds a Fable weekly meter, an original GCD identity, larger dashboard text, contextual prompt history and a native dock duration picker.

• Click the token card or right-click the Windows dock to change its rolling interval.
• Click a prompt for a supported browser conversation or captured details. Coding logs retain a details fallback.
• Internal browser/context wrappers are removed before preview extraction. Existing previews are repaired without replaying token usage; context-only records remain background activity.
• Provider/account ownership checks and restricted conversation links harden history handling. See the security review for dependency maintenance notices and trust limits.
• Includes the six-page manual, also linked near the top of the repository README.

Local validation: 82 Rust tests, 13 frontend tests, Svelte/TypeScript checks, synthetic native context/detail checks, interval totals against SQLite, and dashboard permission/navigation checks. Physical mixed-DPI behavior and provider-specific browser account access remain device checks.

These are unsigned/ad-hoc-signed personal previews. Browser-only conversations require explicit exports; exact browser token usage and automatic cloud synchronization are unavailable.
