pzzacode 0.2.54

What changed in 0.2.54

• The macOS traffic lights are now centered in the top bar with equal top, left and bottom insets and the same gap to the brand. The position is measured on-device instead of guessed, and the brand inset collapses in fullscreen where the lights leave the window.
• The first-run tour tooltip no longer teleports on open: the centered popup keeps its offset through the enter animation, the anchor measurement is confirmed on the next frame, and keyboard focus never scrolls the page.
• OpenCode usage cards now show a masked API key fingerprint (first and last characters only, the secret never leaves the backend). Every local key - the connected account plus each export in ~/.opencode-keys - gets its own card, so multiple subscriptions on one machine and across devices are easy to tell apart. Cards with different fingerprints are kept side by side.
