glowup v1.2.0

Added

• /glowup music, or o: Player on the Music tab, opens a music player: a pane with a bigger cover, the seek bar, the controls, Open Spotify (o) and Copy link (c), and on macOS a volume bar.
• /glowup spotify connect connects your own Spotify developer app (Premium needed). The Music tab and player then follow playback on any device, show a heart to like the track (l) and the next track in your queue, and fall back to the local app while the Web API is not answering. Windows gets the player this way. See docs/spotify.md.
• With Spotify connected, the music player lists Up next, Recent, Playlists and Devices (1 to 4). Enter skips forward to a queued track, replays a recent one in its playlist or album, starts a playlist, or moves playback to another device.
• The Pets page and the landing page show Clawd dancing to music and his two idle variants.

Changed

• The ghost and the robot walk left with hand-drawn frames instead of a mirrored right walk, so they stay lit from the top left like Clawd.

Fixed

• The landing page's hop, fail and scrunch cards replay instead of freezing on their last frame.
