Description

Add true keyboard-driven token lookup flow in overlay:

• Toggle keyboard token-selection mode and navigate tokens by keyboard (Arrow + HJKL).
• Toggle Yomitan lookup window for selected token via fixed accelerator (Ctrl/Cmd+Y) without requiring mouse click.
• Preserve keyboard-only workflow while popup is open by forwarding popup keys (J/K, M, P, [, ]) and restoring overlay focus on popup close.
• Ensure selection styling and hover metadata tooltips (frequency/JLPT) work for keyboard-selected token.

Acceptance Criteria

• #1 Keyboard mode toggle exists and shows visual selection outline for active token.
• #2 Navigation works via arrows and vim keys while keyboard mode is enabled.
• #3 Lookup window toggles from selected token with Ctrl/Cmd+Y; close path restores overlay keyboard focus.
• #4 Popup-local controls work via keyboard forwarding (J/K, M, P, [, ]), including mine action.
• #5 Frequency/JLPT hover tags render for keyboard-selected token.
• #6 Renderer/runtime tests cover new visibility/selection behavior, and docs are updated.

Final Summary

Implemented keyboard-driven Yomitan workflow end-to-end in renderer + bundled Yomitan runtime bridge. Added overlay-level keyboard mode state, token selection sync, lookup toggle routing, popup command forwarding, and focus recovery after popup close. Added popup-visible detection improvements and CSS/test updates for keyboard-selected tooltip behavior. Updated user docs/README to document fixed keyboard workflow shortcuts.
